This commit adds a new --oom-score-adj option to start-stop-daemon and supervise-daemon, as well as an equivalent SSD_OOM_SCORE_ADJ environment variable. If either of these are specified (with the command-line option taking precedence), then the specified adjustment value is written to /proc/self/oom_score_adj after forking but prior to exec'ing the daemon (at the time when nice and ionice are applied). Additionally, per a suggestion by Mike Frysinger, the suggested values for the SSD_NICELEVEL, SSD_IONICELEVEL, and SSD_OOM_SCORE_ADJ variables in the example config file are now given as zeros, which are the kernel's default values of these process knobs for the init process at boot. Note that uncommenting any of these zero-valued suggestions will cause SSD/SD to set the corresponding process knob affirmatively to zero, whereas leaving the variable unset (and the equivalent command- line option unspecified) means SSD/SD will not change the corresponding process knob from its inherited value. See: https://github.com/OpenRC/openrc/pull/435#discussion_r688310672 This fixes #435. |

OpenRC README
OpenRC is a dependency-based init system that works with the
system-provided init program, normally /sbin/init.
building and installing
OpenRC uses the meson build system, so use the usual methods for this build system to build and install.
The old build system is still available for the 0.44.x branch, but it is considered deprecated and will be removed. The previous documentation is below.
Installation (historical)
OpenRC requires GNU make.
Once you have GNU Make installed, the default OpenRC installation can be executed using this command:
make install
Configuration (historical)
You may wish to configure the installation by passing one or more of the below arguments to the make command
PROGLDFLAGS=-static
LIBNAME=lib64
DESTDIR=/tmp/openrc-image
MKBASHCOMP=no
MKNET=no
MKPAM=pam
MKPREFIX=yes
MKPKGCONFIG=no
MKSELINUX=yes
MKSTATICLIBS=no
MKSYSVINIT=yes
MKTERMCAP=ncurses
MKTERMCAP=termcap
MKZSHCOMP=no
PKG_PREFIX=/usr/pkg
LOCAL_PREFIX=/usr/local
PREFIX=/usr/local
BRANDING=\"Gentoo/$(uname -s)\"
SH=/bin/sh
Notes
We don't support building a static OpenRC with PAM.
You may need to use PROGLDFLAGS=-Wl,-Bstatic on glibc instead of just -static
(This is now handled by the meson build system).
If you are building OpenRC for a Gentoo Prefix installation, add MKPREFIX=yes
(this is not supported in the meson build currently, but patches are welcome).
PKG_PREFIX should be set to where packages install to by default.
LOCAL_PREFIX should be set to where user maintained packages are.
Only set LOCAL_PREFIX if different from PKG_PREFIX.
PREFIX should be set when OpenRC is not installed to /.
If any of the following files exist then we do not overwrite them
/etc/devd.conf
/etc/rc
/etc/rc.shutdown
/etc/conf.d/*
rc and rc.shutdown are the hooks from the BSD init into OpenRC.
devd.conf is modified from FreeBSD to call /etc/rc.devd which is a
generic hook into OpenRC.
inittab is the same, but for SysVInit as used by most Linux distributions.
This can be found in the support folder.
Obviously, if you're installing this onto a system that does not use OpenRC by default then you may wish to backup the above listed files, remove them and then install so that the OS hooks into OpenRC.
