A little off the direct topic, but using symlinks can cause trouble-
I've been using mount --bind lately instead of symlinks since I've
found a couple of instances where symlinking gave trouble.
You (Rick) certainly don't need an example, but here's an example of
converting a symlink to a bind-mount for those who aren't old hands:
# ls -l /usr
lrwxrwxrwx 1 root root 12 2010-07-18 21:15 /usr -> /raid488/usr
# mv /usr /usr.old && mkdir /usr && mount --bind /raid488/usr /usr
# cat /etc/mtab |grep usr
/raid488/usr /usr none rw,bind 0 0
# cat /etc/mtab |grep usr >> /etc/fstab
I was a little reckless and didn't go to runlevel 1 before doing this
but didn't suffer any harmful effects (yet)
 AppArmour on last couple of revs of Ubuntu- broke network-manager
IIRC when I moved /usr from its original partition to a larger one and
/usr was made a symlink.
 vsftpd on a legacy system would not follow symlinks- it was a
