[Samba] mount -o remount /mnt/samba creates duplicate mount

[Kyle Schmitt]

This is a repost, since I'd really like to get some info about whats going on.
when using, "mount -o remount" on an linux box, I get a duplicate
mount instead of a proper remount.
/proc/mounts backs me up: the system really does have multiple mounts
in the same place, of the same drive.

The version of samba installed is 3.0.10, the distro is RedHat
Enterprise Linux 4, kernel is 2.6.9-42.EL.

Thanks,
