Bug #2839: Fsck now allows multiple system DS in the same cluster
(cherry picked from commit 544d155fbbf438e59fe88089bc9e46ebb8113bf6)
Restart each interface in ubuntu context

Ubuntu does not support restarting network and it needs to
restart each of the interfaces. In debian restarting the network
works and will continue to use the same method.

lsb_release command is not used as it is not installed by default
in debian.
