When shutting down the computer fisher will sometimes not properly unmount
all the volumes. This can be duplicated by mounting a file as a loopback
/dev/hda1 will be /
/dev/hda2 will be /usr/local
then at the command line
mount -o loop /usr/local/cd/fisher-disc1.iso /mnt/cdrom
/ will unmount but /usr/local/ will not.
We (Red Hat) should really try to resolve this before next release.
Should be fixed in initscripts-5.64-1.
