For OP - Bazzite works a little differently as an immutable OS. Basically only a small handful of directories are editable, and the immutable nature is intended to help provide stability, particularly for users who don’t want to tinker as much (at least that’s my understanding).
Here’s their documentation on auto mounting drives. You’ll probably want the link titled “KDE Partition Manager Guide” under GUI Methods.
But you can edit /etc/fstab
as suggested here, and I’ve done it that way. Just need to mount it under /var/mnt/
and disregard locations recommended by guides that pertain to other distros.
Edit: just saw someone else posted the same link, whoops!
As someone new to both, I’m commenting to hear your answer to the other person’s “why?” :)
