Squid doesn't start on boot sometimes

[rihad]

Just the subj. On my home desktop, approximately once every 10-15 reboots it fails to start and requires manual intervention.. Only one line logged to /var/log/squid/cache.log when it fails to start:

2013/05/04 09:33:51| Starting Squid Cache version 2.7.STABLE9 for x86_64-pc-linux-gnu...

$ dmesg | fgrep squid
[ 25.458786] init: squid main process (1461) killed by HUP signal

Kubuntu 11.10 Oneiric

Please fix this embarrassing bug.

I think I narrowed down the bug to file /etc/resolvconf/update-libc.d/squid

#!/bin/sh

PATH="/usr/sbin:/usr/bin:/sbin:/bin"

# Move to the spool directory to avoid core dump in resolvconf
cd /var/spool/squid

# Make squid aware of changes to resolv.conf
if status squid | grep "start/running" > /dev/null; then
reload squid
fi

/etc/resolv.conf is a symlink to /etc/resolvconf/run/resolv.conf
which never changes logically, it's always nameserver 127.0.0.1 although its mtime does change upon reboot.
It seems that resolvconf doesn't take that into consideration and still sends HUP to squid too early during its startup phase, so it exits sometimes.
I added sleep 10 before reload squid, hope this will work around the issue.
