permissions - Linux - Mount device with specific user rights

How can I mount a device with specific user rights on start up? I still have some problems figuring it out. I would like to mount the divide with uid=1000 and gid=1000. My current entry to the /etc/fstab/ file looks like this:

dev /var/www vboxsf rw, suid, dev, exec, auto, nouser, async, uid=1000

Answer

To mount a device with certain rights, you can use the -o Option directive while mounting the device. To mount the device you described, run:

 mount -t deviceFileFormat -o umask=filePermissions,gid=ownerGroupID,uid=ownerID /device /mountpoint

For example mounting a VirtualBox shared folder to /var/www with www-data as owner would look like this:

mount -t vboxsf -o umask=0022,gid=33,uid=33 dev /var/www

If you want to mount the device on startup, you can add the following entry to your /etc/fstab file:

 /device /mountpoint deviceFileFormat umask=filePermissions,gid=ownerGroupID,uid=ownerUserID

Again, with the same example the entry to the /etc/fstab file would look like this:

dev /var/www vboxsf umask=0022,gid=33,uid=33

For filesystems that does not support mounting as a specific user (like ext4) the above will give the error

Unrecognized mount option "uid=33" or missing value

to change the owner of an ext4 mount simply run

chown username /mountpoint

after it has been mounted.
