I wonder whether the --with-ssh-initscript configure option can
be used to solve your problem in a clean way. Also note that Ganeti
from 2.12 onwards (yes, only about to reach beta1) has support for use
with systemd; Apollon should know most about the details of systemd
support.

Unfortunately you cannot use --with-ssh-initscript directly with systemd, 
because the arguments in systemd are in reverse order ("systemctl restart 
sshd.service"). On Debian it will work because we have transparent wrappers 
around the initscripts and/or invoke-rc.d.

What ganeti could do to resolve this, would be to deprecate 
--with-ssh-initscript and replace it with "--with-ssh-restart-command" and 
accept the full command restarting the ssh service.
