Old log files

[Jason Bassett]

Hello list

Today my Squid/Squidguard machine stopped working.  I tracked it down to a 
full up hard disk so I have deleted some unrequired files.  Although, my 
/var/logs/ folder contains 300Mb of logs.

Many of these are old logs such as access.log.2.gz.

Is it safe to delete all old .gz log files, including the non 
Squid/Squidguard ones?

Thanks

Jason
