This feature is deprecated, but if users use it, they are likely to be tripped up by the wrong selinux context, so add a note. https://discussion.fedoraproject.org/t/systemd-rc-local-service-doesnt-work-on-fedora-40-until-selinux-contexts-are-set-on-rc-local-script

<title>Description</title>
|
||
|
||
<para><command>systemd-rc-local-generator</command> is a generator that checks whether
|
||
<filename>&RC_LOCAL_PATH;</filename> exists and is executable, and if it is, pulls the
|
||
<filename>rc-local.service</filename> unit into the boot process. This unit is responsible for running
|
||
this script during late boot. The script is run after <filename>network.target</filename>, but in
|
||
parallel with most other regular system services.</para>
|
||
|
||
<para>Note that <filename>rc-local.service</filename> 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.</para>
|
||
|
||
<para>Also note that <filename>rc-local.service</filename> is ordered after
|
||
<filename>network.target</filename>, which does not mean that the network is functional, see
|
||
<citerefentry><refentrytitle>systemd.special</refentrytitle><manvolnum>7</manvolnum></citerefentry>.
|
||
If the script requires a configured network connection, it may be desirable to pull in and order it after
|
||
<filename>network-online.target</filename> with a drop-in:</para>
|
||
|
||
<programlisting># /etc/systemd/system/rc-local.service.d/network.conf
|
||
[Unit]
|
||
Wants=network-online.target
|
||
After=network-online.target
|
||
</programlisting>
|
||
|
||
<para>Support for <filename>&RC_LOCAL_PATH;</filename> is provided for compatibility with specific
|
||
System V systems only. However, it is strongly recommended to avoid using 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.</para>

<title>Notes</title>
|
||
|
||
<para>On systems with SELinux, when creating the file, make sure to set the appropriate context, e.g.
|
||
with "<command>sudo restorecon -v &RC_LOCAL_PATH;</command>".
