Hi, something that bothers me a bit... More and more system restart
requests with each update (even if one doesn't use the package at the
time).
Is this necessary for dhclient and dhcp update packages to require
restart?
Wouldn't "service network restart" and "service dhcpd restart" in the
install/upgrade
scripts do the trick (after checking that the service is actually
running)?
Ssh used to do that since, well, as far as I remember.
Yes, 'service dhcpd restart' will work fine for dhcpd. For dhclient, it's
not necessarily as simple as restarting the network service. If you are
using
the network service, that will work fine. If you are using NetworkManager,
you'll need to either restart NetworkManager or have it down the connection
you're using dhclient on and bring it back up.
Why is a restart of NetworkManager necessary in this case? If dhclient
reinitializes the interface and gets the old dhcp data then nothing really
changes and NetworkManager shouldn't have to care. If e.g. der IP changes
then NetworkManager should detect that and reinitialize the connection info
on its end (after all the "new" interface might not be connected to
anything and thus have to be marked as down anyway).
