Package: ifupdown
Version: 0.7.50
Severity: normal
Dear Maintainer,
please consider returning exit status 1 when the up command of an
interface fails. Since the interface is not marked as configured,
network-manager will think there is no connectivity and programs
interacting with NM won't work (for example pidgin).
My situation was that I wanted to turn on jumbo frames for my network
bridge, and I mistakenly added the up commands in the wrong order:
up ifconfig br0 mtu 9000
up ifconfig eth0 mtu 9000
Now on the next reboot network-manager thought I was offline. The reason
for that was a little difficult to debug because systemd thought
everything was just fine: no error was reported from
/etc/init.d/networking. Since my computer boots up too fast to watch the
initialization messages, I didn't notice the error there either. And I
did not suspect ifup as the culprit because I did have a working network
access.
Yes, the man page mentions that this is expected behavior. But given
that it is difficult to debug, and there is real breakage when
network-manager is used, I think that it would be preferable to actually
return an error.
Thanks,
~David
