When you do a sup with "old delete", it will not delete files that
weren't listed in /usr/sup/current/last.allsrc. Otherwise sup would
routinely blow away all of your kernel configs, package distfiles,
backups, objects and so on.

One solution: you could run "cd /usr; find src | sort | diff -U0 -
/usr/sup/current/last.allsrc" after sup'ing to see what got missed.
Another possibility is to use find to _generate_ last.allsrc, edit out
anything you really want to keep, and then do a 'sup -do'.

Of course if you sup exclusively, this is not a problem.
