Just about any FreeBSD

>Description:

The scripts /etc/weekly and /etc/monthly very kindly keep the logs to
managable sizes by truncating/rotating them, and deleting the really old
crud. The problem is, these files still waste space. The root parition is
usually quite small (on installation one is advised to keep it so), so
bunches of these things can be a pain.

>How-To-Repeat:

Run any FreeBSD system for an appreciable length of time...

>Fix:
	
Compress (gzip) the buggers!

Here are patches to etc/daily, etc/weekly and etc/monthly to do this
job: (please note that you should gzip -9n all your <logfile>.[0-9]'s
before doing this!  If you don't, you will just keep forever the old crud.
