Mount partitions for only one user

Question

Like the title says, is there a way to mount a partition (on boot or on login) for only one user, so that other users can't access the files but only me?

I searched for some fstab parameters but i found nothing I that would help.

Answer 1

Depending on what file system you are using for the mounted partition you can use the mount options gid=XX,uid=XXXX (group-id and user-id) - see man mount for more information on what file systems support them. Users are listed in /etc/passwd while groups are listed in /etc/group. For your user, you can use the id command. You can then set the umask-like options to set file permissions.

Here is an example of using them in /etc/fstab:

UUID=<xxxxx> /media/win ntfs rw,auto,nls=utf8,umask=077,gid=46,uid=1000    0   0

And here the same as a mount command:

sudo mount -U <xxxx> -t ntfs -o rw,auto,nls=utf8,umask=077,gid=46,uuid=100 /media/win

File systems that don't have gid and uid as an option, usually can have their rights set in the normal way after you mounted the partitionm i.e. recursively for all files with chmod go-rwx -R /media/mountpoint (or what ever other mountpoint suits your fancy).
