How do you mount a drive in Ubuntu Core? Can you use the fstab? Or is there another way? I don't want to get started an realise you cannot mount an external drive.

When you're in the fstab, it says not to manually write it and to go to /etc/writable but how do you add the fstab? HERE BE DRAGONS I fear

  • /etc/writeable does not exist on my 16.04, and fstab contains no such warning. What OS are you running?

use the systemd to mount a drive on Ubuntu Core 16.04:

Step 1: Identlify your uuid by using

sudo blkid

Step 2: Using "vi" or another editor create a mount unit file for systemd to use. If you want the mount point to be "/media/data" then create the file "/etc/systemd/system/media-data.mount"

sudo vi /etc/systemd/system/media-data.mount

Step 3: Add information about your drive to the mount unit file (media-data.mount)

Description=Mount unit for data



Step 4: reload systemd

sudo systemctl daemon-reload

Step 5: Start the unit

sudo systemctl start media-data.mount

Step 6: To enable auto mount do:

sudo systemctl enable media-data.mount

Step 7: Have fun.
