Bug#751636: ssh sessions are not cleanly terminated on shutdown/restart with systemd

[rihad]

It's very surprising that this bug hasn't been addressed for more than a 
year. This ssh connection hangup never happens under FreeBSD, for 
instance. systemd may just be too buggy, since it has another design 
deficiency, namely being unable to save system time upon reboots (along 
the lines of "hwclock --systohc") because its stupid design prevents 
/etc/init.d/hwclock.sh from running out of the box. Just mentioning 
another unrelated core bug that I have personally encountered.
