yes, mount devices several times it would be a nice feature, but do something like:
/etc/fstab: /dev/hdd1 /mydrive ext2 ro,noauto,user 1 1
as user: mount /mydrive as root: mount /dev/hda2 /mydrive as user: mount /mydrive as root: mount /dev/hda2 /mydrive as user: mount /mydrive
result /proc/mounts: /dev/hdd1 /mydrive ext2 ro,noexec,nosuid,nodev 0 0 /dev/hda2 /mydrive vfat rw 0 0 /dev/hdd1 /mydrive ext2 ro,noexec,nosuid,nodev 0 0 /dev/hda2 /mydrive vfat rw 0 0 /dev/hdd1 /mydrive ext2 ro,noexec,nosuid,nodev 0 0
u dont have control about the mountpoints
Here a BIG PROBLEM: as user: mount /mydrive as root: mount /dev/hdd1 /test as root: mount /dev/hdd1 /mnt
result /proc/mounts: /dev/hdd1 /mydrive ext2 ro,noexec,nosuid,nodev 0 0 /dev/hdd1 /test ext2 ro,noexec,nosuid,nodev 0 0 /dev/hdd1 /mnt ext2 ro,noexec,nosuid,nodev 0 0
but do like mount -o remount /mnt -w
result /proc/mounts: /dev/hdd1 /mydrive ext2 rw 0 0 /dev/hdd1 /test ext2 rw 0 0 /dev/hdd1 /mnt ext2 rw 0 0
ALL mountpoints now READ-WRITE-able!
u lost noexec... and dont have more "security" for users... same as sym-links ... no new feature...
