Are you saying that /var is owned by 'nobody'?

That sounds like a problem for the system to me.  /var should be owned by
root; if you want to have subdirectories owned by 'nobody', or with
permissions to let 'nobody' write to them, that's okay, but I think /var being
owned by 'nobody' will cause more problems than just for squid.

Maybe someone more familiar with squid than I am can comment on this, but
isn't the log file opened before squid drops its privileges (same as the
network sockets), so you don't actually need the logfile path to be writable
by the squid_effective_user?

Antony.
