	That's from the system on which send-pr was run, and isn't relevant.
Architecture: i386
Machine: i386
	If process accounting is enabled, large accounting files
	accumulate in /var/account.   /etc/daily deals with that
	by saving the last 4 days worth, (and summarising the data
	into the summary files using sa).

	The accountig files can be very large - especially on a system
	which isn't necessarily running every day when /etc/daily would
	be run, and so can accumulate many days worth of process info.
	The also gzip very well.

	Doing "gzip /var/account/acct.?" is an easy way to recover lots
	of space on /var, without losing any information.   But once done,
	those gzip'd files are retained until some human action intervenes.
	Files that aren't gzip'd accumulate again.   Thus, after a few
	days, gzip'ing the files results in gret
	/etc/rc.d/accounting forcestart	;# if not enabled already
	gzip /var/account/acct.?
	sleep 345600 ; # 4 days
	ls -l /var/account

	The patch appended has /etc/daily notice if the accunting archive
	files have been gzip'd, and if so, processes them gzip'd.   It doesn't
	add functionality to decide the files should be gzip'd, that remains
	for the user to do manually.
