We have a networked linux computer lab where we need to support users
with floppies of different file system types.
/etc/fstab looks like...

...some nfs stuff...
/dev/fd0  /drivea  msdos  user,conv=auto
/dev/fda  /floppy  ext2   user
#  where fda is exactly like fd0 (same major and minor #'s)

when a user mounts a dos floppy on /drivea the directory perms &
ownerships get changed to:
drwx------  ... jch  users .... /drivea
which allows that user to read/write to the disk
this doesn't happen when a user mounts an ext2fs...
my question is...
would it be insane to change the perms and ownership on the /floppy
directory (where ext2's get mounted)
to something like...
drwxrwx--- ... root users ... /floppy
(to allow the user to write to his/her own floppy without making it
necessary that they be root...)
and/or is there a better way to do this...
thanks, jch
note: we are using the debian fixed version of mount (that fixes the
recent mount hole) on a slackware distribution.
