Hi,

I think that /etc/network/if-pre-up.d/whereami will only run for the
interfaces configured in /etc/network/interfaces, and it won't run when
'lo' is configured.

For many people using whereami lo is the _only_ interface configured, so
whereami needs to run at some point during boot, hence the init script.

Certainly, whereami runs too often during boot, and I'm guilty of not
really seeing that problem since I rarely reboot...

Only three opportunities in September and two in August to notice those
sorts of annoyances, and this laptop is really flakey compared with my
last one.

Consequently that sort of thing is unlikely to change without a patch,
and I do rarely notice problems with the way whereami runs on boot.

I guess it could do something more intelligent in the init script and
just exit if it saw there was a non-lo interface which was going to
cause whereami to run with network initialisation.  That's probably the
right fix, so if you want to look into it and send me a patch :-)

Cheers,
					Andrew.
