Unknown $NAME variable in squid upstart script

Binary package hint: squid

1. Ubuntu Lucid Server AMD64 Alpha 2
2. squid 2.7.STABLE7-1ubuntu6
3. I expected squid to start without cosmetic errors
4. Squid starts, but with the following cosmetic error:

Cannot open /etc/squid/.conf: No such file

This is due to the $NAME variable not being defined on line 36 in /etc/init/squid

Line 36 is originally:
sq=/etc/squid/$NAME.conf

To fix the error it can be modified to:
sq=/etc/squid/squid.conf

Alternatively, change line 42 to the following:
:end q' < $sq` 2> /dev/null

That fixes the cosmetic error, but I think the first fix is probably what's intended by this function.

Thanks,
Mark
