>Description:

/var/db/mountdtab is not removed on bootup, and so hosts "appear" to be
mounting drives when they aren't doing so.

>How-To-Repeat:

set up the nfs server stuff on host 'A',
export a drive/directory to host 'B',
mount host_a:/whatever on host 'B',
unmount,
reboot host 'A', wait for it to come back up
type 'showmount host_a'.

perhaps mountd should remove a client's entry from /var/db/mountdtab
when the client umounts?
