I am familiar with the benefits of having a separate /home partition when performing system reinstalls; the / directory is wiped out with the new system files, but user data is preserved in /home. I am performing a clean Kubuntu install, and would like to make sure I can do this. I am not familiar with LVM options; in other Linux distributions, I have used separate partitions.

The install options are:

  • Guided - use entire disk
  • Guided - use entire disk and set up LVM
  • Guided - use entire disk and set up encrypted LVM
  • Manual

Does one of these guided options allow me to separate the /home partition so reinstallations in the future go smoothly? Do I need to make changes once installation is completed to achieve this? Or is it simpler to just use the manual option?

The "guided" descriptor seems poor. Selecting any of these options is a final decision; there are no further options for modifying the disk configuration after making a guided selection.

No - the guided options will not let you create (or recover) a separate /home. Both of these tasks have to be done through the "Manual" method (so you can choose to mount, but not format /home next time). YMMV and assuming a modern disk, Set up at least 3 partitions (use an extended partition):

swap I recommend 3x RAM
/ I use 32G 44% full (if I have it)
/home the remainder.
