Hi and thanks for the quick reply ! I've added the šEnvironment=INIT_VERSION=sysvinit-1234 in my units and now I can control the reboot/poweroff/halt of my system !

It could be related to the fact that this is not enough. Standard halt command from sysvinit behaves differently depending whether it is called by user or by /sbin/init. When called by user it simply pokes init via initctl which then re-executes halt once more and this time it really preforms halt. The check is š š š š/* š š š š * š š šFirst see if we were started directly from init. š š š š */ š š š šif (getenv("INIT_VERSION") && (r = getenv("RUNLEVEL")) != NULL) So on Mandriva I had to add INIT_VERSION to reboot/halt/poweroff units to make systemd coexist with sysvinit utilities. </blockquote></div>
