systemd-rc-local-generator, rc-local.service — Compatibility generator and service to start
/etc/rc.d/rc.local during boot
systemd-rc-local-generator is a generator that checks whether
/etc/rc.d/rc.local exists and is executable, and if it is, pulls the
rc-local.service unit into the boot process. This unit is responsible for running
this script during late boot. The script is run after
network.target, but in
parallel with most other regular system services.
rc-local.service runs with slightly different semantics than the
original System V version, which was executed "last" in the boot process, which is a concept that does
not translate to systemd.
Also note that
rc-local.service is ordered after
network.target, which does not mean that the network is functional, see
If the script requires a configured network connection, it may be desirable to pull in and order it after
network-online.target with a drop-in:
# /etc/systemd/system/rc-local.service.d/network.conf [Unit] Wants=network-online.target After=network-online.target
/etc/rc.d/rc.local is provided for compatibility with specific System
V systems only. However, it is strongly recommended to avoid making use of this script today, and instead
provide proper unit files with appropriate dependencies for any scripts to run during the boot process.
Note that the path to the script is set at compile time and varies between distributions.
