this is fixed in the meantime so that the current sshd
process with your sessions get's no longer killed, this
problem was introduced with systemd F16/F17 upgrade and
is a very good example for "not do it this way" because
it killed also "yum complete-transaction" repeatly

fact is you have NO IDEA in a larger update what happens
if services are restarted randomly and so it is very bad
to go this windows way and make admins life harder

bother the ordinary GUI user with OfflineSystemUpdates* but
leave us yum-admin-folks completly in peace at all while
assume that we are knowing what we are doing - keep your
fingers as much off my environment as possible
