===========
|
|
|
|
This file will contain a list of notable changes for each release. Note
|
|
the information in this file is in reverse order.
|
|
|
|
## OpenRC 0.43
|
|
|
|
This version changes the behavior of the checkpath helper to address
|
|
CVE-2018-21269. on Linux systems, We require non-terminal symbolic links
|
|
to be owned by root. Since we can't do this on non-linux xystems, we do
|
|
not dereference non-terminal symbolic links by default. If you need them
|
|
dereferenced, you should add the "-s" switch to the appropriate
|
|
checkpath calls.
|
|
For more information, see http://github.com/openrc/openrc/issues/201.
|
|
|
|
The SHLIBDIR variable has been removed from the makefiles to make them
|
|
more consistent with most common makefiles. All libraries are now in
|
|
LIBDIR, so if you need to put them in /, override the LIBDIR variable
|
|
when you run make.
|
|
|
|
## OpenRC 0.42
|
|
|
|
openrc-shutdown now has the ability to shut down sysvinit-based systems.
|
|
|
|
A guide has been added for migrating systems using another init system
|
|
to openrc-init.
|
|
|
|
## OpenRC 0.41.
|
|
|
|
This version adds the ability to format the output of rc-status when
|
|
showing the status of services in a runlevel so that it may be parsed.
|
|
Currently, the -f switch only accepts ini as an argument which
|
|
causes the output to be in the .ini format.
|
|
|
|
This version adds an experimental build time switch to allow setting the
|
|
default shell to use for service scripts.
|
|
By default, this is set to /bin/sh if it is changed, the new shell must
|
|
be able to understand posix-compatible syntax.
|
|
|
|
## OpenRC 0.40
|
|
|
|
In this version, the keymaps and termencoding services on Linux needed
|
|
to be modified so they do not write to the root file system. This was
|
|
done so they can run earlier in the boot sequence. AS a result, you will
|
|
need to add save-termencoding and save-keymaps to your boot runlevel.
|
|
This can be done as follows:
|
|
|
|
```
|
|
# rc-update add save-keymaps boot
|
|
# rc-update add save-termencoding boot
|
|
```
|
|
|
|
## OpenRC 0.39
|
|
|
|
This version removes the support for addons.
|
|
The only place I know that this was used was Gentoo Baselayout 1.x, so
|
|
it shouldn't affect anyone since baselayout-1 has been dead for a few
|
|
years.
|
|
|
|
Since all supported Linux kernel versions now make efivarfs immutable
|
|
and all of the tools that access efivarfs are aware of this, we no
|
|
longer mount efivarfs read-only. See the following github issue for more
|
|
information:
|
|
|
|
https://github.com/openrc/openrc/issues/238
|
|
|
|
This version adds timed shutdown and cancelation of shutdown to
|
|
openrc-shutdown. Shutdowns can now be delayed for a certain amount of
|
|
time or scheduled for an exact time.
|
|
|
|
supervise-daemon supports health checks, which are a periodic way to make sure a
|
|
service is healthy. For more information on setting this up, please see
|
|
supervise-daemon-guide.md.
|
|
|
|
The --first-time switch has been added to all modprobe commands in the
|
|
modules service. This means that, on Linux, you will see failures if a
|
|
module was loaded by an initramfs or device manager before this service
|
|
runs. These messages are harmless, but to clean them up, you should adjust your
|
|
modules autoload configuration.
|
|
|
|
## OpenRC 0.37
|
|
|
|
start-stop-daemon now supports logging stdout and stderr of daemons to
|
|
processes instead of files. These processes are defined by the
|
|
output_logger and error_logger variables in standard service scripts, or
|
|
by the -3/--output-logger or -4/--error-logger switches if you use
|
|
start-stop-daemon directly. For more information on this, see the
|
|
start-stop-daemon man page.
|
|
|
|
## OpenRC 0.36
|
|
|
|
In this release, the modules-load service has been combined into the
|
|
modules service since there is no reason I know of to keep them
|
|
separate. However, modules also provides modules-load in case you were
|
|
using modules-load in your dependencies.
|
|
|
|
The consolefont, keymaps, numlock and procfs service scripts no longer
|
|
have a dependency on localmount.
|
|
If you are a linux user and are still separaating / from /usr,
|
|
you will need to add the following line to the appropriate conf.d files:
|
|
|
|
rc_need="localmount"
|
|
|
|
## OpenRC 0.35
|
|
|
|
In this version, the cgroups mounting logic has been moved from the
|
|
sysfs service to the cgroups service. This was done so cgroups can be
|
|
mounted inside an lxc/lxd container without using the other parts of the
|
|
sysfs service.
|
|
|
|
?As a result of this change, if you are upgrading, you need to add
|
|
cgroups to your sysinit runlevel by running the following command as
|
|
root:
|
|
|
|
```
|
|
# rc-update add cgroups sysinit
|
|
```
|
|
|
|
For more information, see the following issue:
|
|
|
|
https://github.com/openrc/openrc/issues/187
|
|
|
|
Consider this your second notification with regard to /etc/mtab being a
|
|
file instead of a symbolic link.
|
|
|
|
In this version, the mtab service will complain loudly if you have
|
|
mtab_is_file set to yes and recommend that you change this to no and
|
|
restart the mtab service to migrate /etc/mtab to a symbolic link.
|
|
|
|
If there is a valid technical reason to keep /etc/mtab as a flat file
|
|
instead of a symbolic link to /proc/self/mounts, we are interested and
|
|
we will keep the support in that case. Please open an issue and let us
|
|
know however. Otherwise, consider this your final notice that the mtab
|
|
service will be removed in the future.
|
|
|
|
## OpenRC 0.33
|
|
|
|
This version removes the "service" binary which was just a copy of
|
|
"rc-service" provided for compatibility.
|
|
|
|
If you still need the "service" binary, as opposed to "rc-service", it is
|
|
recommended that you use something like Debian's init-system-helpers.
|
|
Otherwise, just use "rc-service" in place of "service".
|
|
|
|
## OpenRC 0.31
|
|
|
|
This version adds support for Control Groups version 2, which is
|
|
considered stable as of Linux-4.13. Please see /etc/rc.conf for
|
|
documentation on how to configure control groups.
|
|
|
|
## OpenRC-0.28
|
|
|
|
This version mounts efivars read only due to concerns about changes in
|
|
this file system making systems unbootable. If you need to change something
|
|
in this path, you will need to re-mount it read-write, make the change
|
|
and re-mount it read-only.
|
|
|
|
Also, you can override this behavior by adding a line for efivars to
|
|
fstab if you want efivars mounted read-write.
|
|
|
|

|
|
|
|
https://github.com/openrc/openrc/issues/134
|
|
|
|
## OpenRC-0.25
|
|
|
|
This version contains an OpenRC-specific implementation of init for
|
|
Linux which can be used in place of sysvinit or any other init process.
|
|
For information on its usage, see the man pages for openrc-init (8) and
|
|
openrc-shutdown (8).
|
|
|
|
## OpenRC-0.24.1
|
|
|
|
This version starts cleaning up the dependencies so that rc_parallel
|
|
will work correctly.
|
|
|
|
The first step in this process is to remove the 'before *' from the
|
|
depend functions in the clock services. This means some services not
|
|
controlled by OpenRC may now start before instead of after the clock
|
|
service. If it is important for these services to start after the clock
|
|
service, they need to have 'after clock' added to their depend
|
|
functions.
|
|
|
|
## OpenRC-0.24
|
|
|
|
Since the deptree2dot tool and the perl requirement are completely
|
|
optional, the deptree2dot tool has been moved to the support directory.
|
|
As a result, the MKTOOLS=yes/no switch has been removed from the makefiles.
|
|
|
|
This version adds the agetty service which can be used to spawn
|
|
agetty on a specific terminal. This is currently documented in the
|
|
agetty-guide.md file at the top level of this distribution.
|
|
|
|
## OpenRC-0.23
|
|
|
|
The tmpfiles.d processing code, which was part of previous versions of
|
|
OpenRC, has been separated into its own package [1]. If you need to
|
|
process systemd style tmpfiles.d files, please install this package.
|
|
|
|
[1] https://github.com/openrc/opentmpfiles
|
|
|
|
## OpenRC-0.22
|
|
|
|
In previous versions of OpenRC, configuration information was processed
|
|
so that service-specific configuration stored in /etc/conf.d/* was
|
|
overridden by global configuration stored in /etc/rc.conf. This release
|
|
reverses that. Global configuration is now overridden by
|
|
service-specific configuration.
|
|
|
|
The swapfiles service, which was basically a copy of the swap service,
|
|
has been removed. If you are only using swap partitions, this change
|
|
will not affect you. If you are using swap files, please adjust the
|
|
dependencies of the swap service as shown in /etc/conf.d/swap.
|
|
|
|
## OpenRC-0.21
|
|
|
|
This version adds a daemon supervisor which can start daemons and
|
|
restart them if they crash. See supervise-daemon-guide.md in the
|
|
distribution for details on its use.
|
|
|
|
It is now possible to mark certain mount points as critical. If these
|
|
mount points are unable to be mounted, localmount or netmount will fail.
|
|
This is handled in /etc/conf.d/localmount and /etc/conf.d/netmount. See
|
|
these files for the setup.
|
|
|
|
The deprecation messages in 0.13.x for runscript and rc are now
|
|
made visible in preparation for the removal of these binaries in 1.0.
|
|
|
|
The steps you should take to get rid of these warnings is to run openrc
|
|
in initialization steps instead of rc and change the shebang lines in
|
|
service scripts to refer to "openrc-run" instead of "runscript".
|
|
|
|
In 0.21.4, a modules-load service was added. This works like the
|
|
equivalent service in systemd. It looks for files named *.conf first in
|
|
/usr/lib/modules-load.d, then /run/modules-load.d, then
|
|
/etc/modules-load.d. These files contain a list of modules, one per
|
|
line, which should be loaded into the kernel. If a file name appears in
|
|
/run/modules-load.d, it overrides a file of the same name in
|
|
/usr/lib/modules-load.d. A file appearing in /etc/modules-load.d
|
|
overrides a file of the same name in both previous directories.
|
|
|
|
## OpenRC-0.19
|
|
|
|
This version adds a net-online service. By default, this
|
|
service will check all known network interfaces for a configured
|
|
interface or a carrier. It will register as started only when all
|
|
interfaces are configured and there is at least a carrier on one
|
|
interface. The behaviour of this service can be modified in
|
|
/etc/conf.d/net-online.
|
|
|
|
Currently, this only works on Linux, but if anyone wants to port to
|
|
*bsd, that would be welcomed.
|
|
|
|
## OpenRC-0.18.3
|
|
|
|
Modern Linux systems expect /etc/mtab to be a symbolic link to
|
|
/proc/self/mounts. Reasons for this change include support for mount
|
|
namespaces, which will not work if /etc/mtab is a file.
|
|
By default, the mtab service enforces this on each reboot.
|
|
|
|
If you find that this breaks your system in some way, please do the
|
|
following:
|
|
|
|
- Set mtab_is_file=yes in /etc/conf.d/mtab.
|
|
|
|
- Restart mtab. This will recreate the /etc/mtab file.
|
|
|
|
- Check for an issue on https://github.com/openrc/openrc/issues
|
|
explaining why you need /etc/mtab to be a file. If there isn't one,
|
|
please open one and explain in detail why you need this to be a file.
|
|
If there is one, please add your comments to it. Please give concrete
|
|
examples of why it is important that /etc/mtab be a file instead of a
|
|
symbolic link. Those comments will be taken into consideration for how
|
|
long to keep supporting mtab as a file or when the support can be
|
|
removed.
|
|
|
|
## OpenRC-0.18
|
|
|
|
The behaviour of localmount and netmount in this version is changing. In
|
|
the past, these services always started successfully. In this version,
|
|
they will be able to fail if file systems they mount fail to mount. If
|
|
you have file systems listed in fstab which should not be mounted at
|
|
boot time, make sure to add noauto to the mount options. If you have
|
|
file systems that you want to attempt to mount at boot time but failure
|
|
should be allowed, add nofail to the mount options for these file
|
|
systems in fstab.
|
|
|
|
## OpenRC-0.14
|
|
|
|
The binfmt service, which registers misc binary formats with the Linux
|
|
kernel, has been separated from the procfs service. This service will be
|
|
automatically added to the boot runlevel for new Linux installs. When
|
|
you upgrade, you will need to use rc-update to add it to your boot
|
|
runlevel.
|
|
|
|
The procfs service no longer automounts the deprecated usbfs and
|
|
usbdevfs file systems. Nothing should be using usbdevfs any longer, and
|
|
if you still need usbfs it can be added to fstab.
|
|
|
|
Related to the above change, the procfs service no longer attempts to
|
|
modprobe the usbcore module. If your device manager does not load it,
|
|
you will need to configure the modules service to do so.
|
|
|
|
The override order of binfmt.d and tmpfiles.d directories has been
|
|
changed to match systemd. Files in /run/binfmt.d and /run/tmpfiles.d
|
|
override their /usr/lib counterparts, and files in the /etc counterparts
|
|
override both /usr/lib and /run.
|
|
|
|
## OpenRC-0.13.2
|
|
|
|
A chroot variable has been added to the service script variables.
|
|
This fixes the support for running a service in a chroot.
|
|
This is documented in man 8 openrc-run.
|
|
|
|
The netmount service now mounts nfs file systems.
|
|
This change was made to correct a fix for an earlier bug.
|
|
|
|
## OpenRC-0.13
|
|
|
|
/sbin/rc was renamed to /sbin/openrc and /sbin/runscript was renamed to
|
|
/sbin/openrc-run due to naming conflicts with other software.
|
|
|
|
Backward compatible symbolic links are currently in place so your
|
|
system will keep working if you are using the old names; however, it is
|
|
strongly advised that you migrate to the new names because the symbolic
|
|
links will be removed in the future.
|
|
Warnings have been added to assist with this migration; however, due to the
|
|
level of noise they produce, they only appear in verbose mode in this release.
|
|
|
|
The devfs script now handles the initial mounting and setup of the
|
|
/dev directory. If /dev has already been mounted by the kernel or an
|
|
initramfs, devfs will remount /dev with the correct mount options
|
|
instead of mounting a second /dev over the existing mount point.
|
|
|
|
It attempts to mount /dev from fstab first if an entry exists there. If
|
|
it doesn't it attempts to mount devtmpfs if it is configured in the
|
|
kernel. If not, it attempts to mount tmpfs.
|
|
If none of these is available, an error message is displayed and static
|
|
/dev is assumed.
|
|
|
|
## OpenRC-0.12
|
|
|
|
The net.* scripts, originally from Gentoo Linux, have
|
|
been removed. If you need these scripts, look for a package called
|
|
netifrc, which is maintained by them.
|
