[Pkg-samba-maint] Bug#652942: dhcp hook runs reload on shutdown

[Roderich Schupp]

Hi Michael and Christian,

while this problem is mildly annoying when using the traditional sysv
init system
it is a major PITA when using systemd.
Systemd turns "invoke-rc.d samba reload" into "systemctl reload samba.service"
which of course cannot work this far into the shutdown sequence.
But it hangs _several minutes_ at that point until apparently a timeout kicks in
and the shutdown proceeds. Sometimes it hangs indefinitely and I have
to resort to sysreq-O or the hardware power button.

Cheers, Roderich
