As per a bug report from a user:

mount.c seems to assume that nfsumount() uses standard C true/false
return values, and inverts them for the exit status (where 0 is
traditionally considered success). However, nfsumount() consistently
seems to use 0 for success, and thus a success gets returned as exit
status 1 and a failure as exit status 0. This confuses at least
the GNOME drive manager applet, and probably others as well.

mount.nfs: Add the mount option "nosharecache"

Prior to David Howell's mount changes in 2.6.18, users who mounted
different directories which happened to be from the same filesystem on the
server would get different super blocks, and hence could choose different
mount options. As long as there were no hard linked files that crossed from
one subtree to another, this was quite safe.
Post the changes, if the two directories are on the same filesystem (have
the same 'fsid'), they will share the same super block, and hence the same
mount options.

Add a flag to allow users to elect not to share the NFS super block with
another mount point, even if the fsids are the same. This will allow
users to set different mount options for the two different super blocks, as
was previously possible. It is still up to the user to ensure that there
are no cache coherency issues when doing this, however the default
behaviour will be to share super blocks whenever two paths result in

Add --with-rpcgen= for configure so that the system rpcgen can be used.

Ultimately it makes sense to remove remove rpcgen from the nfs-utils
release as it is already in the glibc release.  With this patch
you can use the system rpcgen to make sure it works.
It is not default yet, but it might be in a future release.

Handle -o remount better

On -o remount, we need to update the entry in mtab rather than
add a new one.  update_mtab does this so use that.
However it might free some strings that shouldn't be freed, so
stop it from calling free - the program will exit soon anyway
so no exit is needed.

Registering sockets with portmap might require root privs,
so don't drop privs until that has been done.
