:I'm a little bit astonished that's now possible to mount via nfs
:several times at the same mountpoint with freebsd nfs clients:
:
:normal behaviour (Linux 2.2, Solaris):
:--------------------------------------
:
:magma:/ # mount magma:/cdrom /mnt
:magma:/ # mount magma:/cdrom /mnt
:mount: magma:/cdrom already mounted or /mnt busy
:
:freebsd behaviour (stable and current):
:---------------------------------------
:
:# mount magma:/cdrom /mnt
:# mount magma:/cdrom /mnt
:# mount magma:/cdrom /mnt
:
:#mount
:/dev/sd0s2a on / (NFS exported, local, soft-updates, writes: sync 9 async 1508)
:/dev/sd0s2e on /var (local, soft-updates, writes: sync 160 async 1695)
:procfs on /proc (local)
:magma:/cdrom on /mnt
:magma:/cdrom on /mnt
:magma:/cdrom on /mnt

:I think this is a very strange behaviour ... any ideas ? And as I know
:loopback mounts are not possible with fbsd. Am I mistaken ?

Well, theoretically there is nothing wrong going on since you can mount
things on top of an NFS directory. Mount only complains about
duplicate normal partition mounts because it can't open the buffered
block device the second time. NFS doesn't care how many times a
directory is imported or exported.
