[systemd-devel] rc-local.service and its future in systemd?

Did you test this yourself? I couldn't get it to work. If I don't 
disable systemd-rc-local-generator,
it'll create a multi-user.target.wants for rc-local.service in 
/run/systemd.
rc-local.service is also referenced in multiple other service files in 
/usr/lib/systemd/system.

I arrived into this following config that is now working:

1)

# /etc/systemd/system/rc-local.service.d/override.conf
[Unit]
After=systemd-user-sessions.service

[Install]
WantedBy=default.target

2)

mkdir /root/systemd
mv /usr/lib/systemd/system-generators/systemd-rc-local-generator 
/root/systemd/
ln -s /dev/null 
/usr/lib/systemd/system-generators/systemd-rc-local-generator

3)

chmod 700 /etc/rc.d/rc.local
systemctl enable rc-local.service

As one Red Hat employee once said: "And I'm pretty sure that the people 
who still insist
on using it would shout at us very loudly if rc-local.service were 
removed...".

I hope rc-local.service can be kept in systemd in the future.

Best regards,

Aki

P.S. My hunch was correct and rc.local is now 
(After=systemd-user-sessions.service) ran after crond.
