  • Suppose you currently use the partition `/dev/sda1` for everything, and you create a new partition `/dev/sda2` to use for `/home`.
  • All you have to do is move your files to the new partition, and make sure it is mounted at `/home` automatically during boot.
  • The automount configuration is in `/etc/fstab` (https://wiki.archlinux.org/title/Fstab). In short, for home you can use something like:
  • ```
  • UUID=abcd1234 /home ext4 rw,relatime 0 2
  • ```
  • Note that it's better to specify the partition with UUID. I am giving examples as `/dev/sda*` for simplicity.
  • You should test this with a dummy folder, like `/home-test`, so that if you make a mistake and it fails to mount you don't end up with a broken homedir.
