@ for root issue

[jacksnodgrass]

I know that this might be too picky / too lose.... but I'll post it anyway. I decided to change my root and home btrfs subvolumes to @ and @home to match the Timeshift openSuse format. I like @ and @home so I went the full monte with:

root@testvm:~# btrfs subvolume list /
ID 256 gen 227 top level 5 path @home
ID 261 gen 231 top level 5 path @
ID 262 gen 234 top level 5 path @var
ID 263 gen 215 top level 5 path @opt
ID 264 gen 227 top level 5 path @srv
ID 265 gen 215 top level 5 path @data
ID 266 gen 215 top level 5 path @usr_local

and then of course since I an off-normal I get:

root@testvm:~# atomic-rollback setup
atomic-rollback: setting up snapshots and rollback

Is that easy fix to allow for @ for root? I think that @ for root is widely acceptable... just not what Fedora does out of the box.

Everything else I've been testing with seems to be working with my current setup.

Thanks - jack

Fixed in v0.3.8. The root filesystem check now reads the subvolume name from your /etc/fstab subvol= option instead of hardcoding "root", so layouts using @ (or any other name) work.

To update:

sudo dnf update atomic-rollback
