a while back i reported an issue where /dev/null was getting set to 600
perms after a system update.  i finally figured out what it is.  i don't
care about failed logins and have limited space on some servers, so i
symlinked /var/log/btmp to /dev/null.  the initscripts package does a
chmod 600 /var/log/btmp, so voila /dev/null gets changed.

so now i know why it happened just to me.  i now need to figure out a
better way to deal with btmp.  any ideas from the list?
