# OpenRC init process guide
|
||
|
|
|
||
|
|
OpenRC now includes an init process which can be used on Linux systems
|
||
|
|
in place of sysvinit.
|
||
|
|
|
||
|
|
## migrating a live system to openrc-init
|
||
|
|
|
||
|
|
Configuring a live system to use this init process is very
|
||
|
|
straight-forward, but the steps must be completed in this order.
|
||
|
|
|
||
|
|
* have your boot loader add "init=/sbin/openrc-init" to the kernel command line
|
||
|
|
|
||
|
|
The details of how to do this will vary from distro to distro, so they are
|
||
|
|
out of scope for this document.
|
||
|
|
|
||
|
|
* Install gettys into the runlevels where you need them.
|
||
|
|
|
||
|
|
If you are using the provided /etc/init.d/agetty script,, you should
|
||
|
|
first create symlinks in /etc/init.d to it for the ports where you
|
||
|
|
want gettys to run, e.g. the following will work if you want gettys on
|
||
|
|
tty1-tty6.
|
||
|
|
|
||
|
|
```
|
||
|
|
# cd /etc/init.d
|
||
|
|
# for x in tty1 tty2 tty3 tty4 tty5 tty6; do
|
||
|
|
ln -snf agetty agetty.$x
|
||
|
|
done
|
||
|
|
```
|
||
|
|
|
||
|
|
Once this is done, use ```rc-update``` as normal to install the agetty
|
||
|
|
services in the appropriate runlevels.
|
||
|
|
|
||
|
|
* Reboot your system.
|
||
|
|
|
||
|
|
At this point you are running under openrc-init, and you should use
|
||
|
|
openrc-shutdown to handle shutting down, powering off, rebooting etc.
|
||
|
|
|
||
|
|
## optional sysvinit compatibility
|
||
|
|
|
||
|
|
If you build and install OpenRC with MKSYSVINIT=yes, you will build and install
|
||
|
|
wrappers that make openrc-init compatible with sysvinit -- you will have
|
||
|
|
commands like "halt" "shutdown" "reboot" and "poweroff".
|
||
|
|
|
||
|
|
If you want this functionality on a live system, you should first
|
||
|
|
migrate the system to openrc-init, remove sysvinit, then rebuild and
|
||
|
|
install this package with MKSYSVINIT=yes.
