Public bug reported:
On Precise, squid3 is started by a upstart job, while bind9 is not.
This causes problem if squid3 needs to do DNS lookups when parsing its
configuration file.
Example: the same machine is a DNS server and a proxy.
The file /etc/squid3/squid.conf contains the following line:
acl myacl src host.name
The bind9 service would be able to resolve host.name, but it may not be
started before squid3. If this happens, squids logs the following error
messages:
[...]
squid3: Bungled squid.conf line 727: acl myacl src host.name
[ 7167.978333] init: squid3 main process (4637) terminated with status 1
[ 7167.978363] init: squid3 main process ended, respawning
squid3: Bungled squid.conf line 727: acl myacl src host.name
[ 7167.995068] init: squid3 main process (4643) terminated with status 1
[ 7167.995098] init: squid3 main process ended, respawning
squid3: Bungled squid.conf line 727: acl myacl src host.name
[ 7168.012017] init: squid3 main process (4649) terminated with status 1
[ 7168.012047] init: squid3 respawning too fast, stopped
This problem consistently appears on my system.

IMHO the solution to this bug should consist of:
1- writing an upstart job for running bind9;
2- letting the squid3 upstart job depend on bind9.
