Running xUbuntu on a SDCard

Finally, I decided to install xUbuntu on a 256GB SDCard as the 16GB built-in emmc drive on a chromebook (Dell P22T) is too small for a desktop system.

Undoubtly, SDCard is slow and easier to be broken. So I took the following actions to the file system and hope they can help solve both issues:

  1. Turning off atime.
  2. Disabling the journal feature.
