This is an issue with squid, not resolvconf.  If squid is providing a
script for resolvconf to run, it need to make sure it work also if
/usr/ is a separate partition and executed before /usr/ is mounted.
The fact that there might be other buggy scripts around do not change
this, and there is nothing resolvconf can do to work around this fact.
The kernel will activate interfaces whenever it want, for example
before /usr/ is mounted, and while resolvconf handle this just fine,
the squid resolvconf script do not.

So I see no point in moving it to resolvconf, and believe the squid
script just need to stop trying to restart squid if /usr/ isn't
mounted.
