Package: initscripts
Version: 2.86.ds1-61
Followup-For: Bug #481028
I recently upgraded to Lenny and noticed the same problem on my machine (albeit
to a lesser extent, as I only have about ten virtual interfaces). I've
observed that the delay problem is not actually the mountnfs script itself
(although it does like to babble); it's that *every* script in if-up.d gets
executed for *every* interface. This means that anyone who has fifty virtual
interfaces gets to run things like openssh-server fifty times. For me,
removing avahi-daemon sped things up quite a lot; it took a couple seconds each
time to restart.
Which leads me to wonder: should these scripts be rewritten to recognize (as
mountnfs does) that there are still interfaces pending and hold off their
operations until the last interface comes up? The script used in mountnfs
could be generalized so that each script simply does something like
is_last_interface || exit 0
at the top (probably with an additional check to ensure that we're actually
bringing everything up and not just in the middle of reconfiguring one
interface) in order to prevent them from being run a bunch of times.
What we really need is to have "ifup -a" set another environment variable (in
addition to the ones listed in the interfaces man page) which indicates whether
or not the current interface being brought up is the last one (such as
NOT_LAST). NOT_LAST would be unset for the last interface of an ifup -a as
well as for any execution of ifup on a single interface (e.g., ifup eth0). But
I don't know how feasible that would be; can anyone make any comments about
that?
Nonetheless, mountnfs is still quite chatty. It could probably mention all of
the interfaces on a single line; that would help a lot. (e.g.:
"if-up.d/mountnfs[eth1:5]: waiting for interfaces before doing NFS mounts:
eth1:6, eth1:7, eth1:8, ...")
Cheers!
