Protecting Data with Encrypted Linux Partitions Part 2 - page 3

Adding Your Own Back Door

While most Linux distributions have a default udev configuration that nails down the /dev names of internal drives, it doesn't hurt to make extra sure by using the UUID instead. So the /etc/fstab entry for our encrypted partition would look like this:

UUID=1c390791-bd8a-4655-b722-6d0bcbbdf547  /home/carla/crypted  ext3 users,atime,noauto,rw,dev,exec,suid   0 0

Note that all of that should be on a single line with no carriage returns or line breaks.

Where do you find the UUID? With the vol_id command:

# vol_id -u /dev/sda2
1c390791-bd8a-4655-b722-6d0bcbbdf547
