Snapper-rollback.conf

[techarmy01]

I was trying to replicate this snapper-rollback with barebone Debian install using netboot iso and then hitting a roadblock with snapper-rollback script.

Question:

I saw the spiral Linux snapper-rollback.conf file and for mountpoint, it says /tmp/snapper-rollback-mnt but this is not mentioned in the /etc/fstab for spiral Linux install.

What is the logic of that mountpoint and how can I replicate with Debian install?

I got all other pieces in place and seem to make sense.

I don't like default snapper rollback where it sets default subvol and boots from it instead replacing the top subvol @ with snapshot which is cleaner and what is recommended by Arch Linux wiki.

Many thanks.
