Actually no, /var/log/messages is not an init system log file; on some Linux
distros it is a default log location for syslog.

I can confirm that squid will write to /var/log/messages if syslog logging is
enabled AND syslog is configured to write to /var/log/messages (this is the
default behaviour on some Linux distributions, such as Debian, but not Ubuntu).
