mount -o remount,rw as user

[Mike McClain <mike.junk@nethere.com>]

On a mostly Etch system with this line in /etc/fstab
    /dev/hda5     /d    msdos   defaults,rw,user,umask=0001      0 0
user mike can mount the partition and write to it but not remount it
read only in any way I can discover.

Same with this line
    /dev/hda5     /d    msdos   defaults,rw,users,umask=0001     0 0

mike@/deb40:~> mount -o remount,ro /d
mount: only root can do that

mike@/deb40:~> ls -l /dev/hda5
brw-rw----  1 mike disk 3, 5 Feb 25  2005 /dev/hda5
This doesn't seem to matter nor did making mike the owner of the
directory (/d) that /dev/hda5 is mounted on.

I'd prefer to mount the partition ro and only remount it rw once a day
to copy some files from another computer via a script.

Any help would be appreciated.

TIA,
Mike
