Correct me, if I'm wrong -- it won't be the first time today ;>
/etc/lrp.conf has a variable: lrp_SPACECHECK=YES/NO -- if YES, then --
and, only then -- /etc/cron.daily/multicron-d and its links can run
checkfreespace(), which calls updatefree(), &c.
Suppose, updatefree() returns a value for which ckfree() returns 0, then
-- and, only then -- cleanlevel() runs and prunes applicable files that
match the filter: $lrp_SC_DEL_L$cklevel
But, *what* files can these be? In /etc/lrp.conf -- by default -- we
see exclusively this:
lrp_SC_DEL_L1="/var/log/*[4-9].gz"
lrp_SC_DEL_L2="/var/log/*[1-3].gz"
lrp_SC_DEL_L3="/var/log/*.gz"
lrp_SC_DEL_L4="/var/log/*.0"
lrp_SC_DEL_L5="/var/log/wtmp"
Notice, *ALL* of these files -- by default -- reside in /var/log !!!
Since *only* files under /var/log can be pruned -- by default -- then,
why not modify updatefree() to say this:
set -- $(df /var/log | sed -n 2p)
What do you think?

Dare to fix things before they break . . .
Our capacity for understanding is inversely proportional to how much we
think we know. The more I know, the more I know I don't know . . .
