[systemd-devel] Systemd port on custom embedded linux

[Cristian Axenie]

Hi !
I've managed to add the proper symlinks in sbin and the
reboot/halt/poweroff/shutdown are now handled by systemctl. I also removed
the INIT_VERSION environment entry from the corresponding units. Should I
consider to keep the entries in the current units (i.e.: /etc/init.d/reboot)
that are unmounting the filesystems or should systemctl handle all the
unmounting actions safely ?

Best !
