I'll agree with this much anyway :-) Ignoring for now how the exports
are managed in the kernel, it is really bad that mountd needs to
know about individual filesystems in order to NFS export them. The
export interface also does not allow the export list to be replaced
atomically, so all of the exports fail briefly when mountd reloads them
on receipt of a SIGHUP.

There is apparently work ongoing to improving the mount(2) interface
(I forget who is doing this). Hopefully this should make it much
easier to arrange for mountd to change the export lists in a
filesystem-independent manner, even if exports are still managed
per-filesystem in the kernel.

However for this bug (ext2fs and hpfs filesystems cannot be un-exported
once they have been exported) I am just looking for a quick solution
for now, but I have already put some thought into improving the
mountd-kernel interface, which is something I really want to see
