These are mostly my notes to remind myself, I'd Highly reccomend watching this-video or reading this arch wiki page
/.snapshots already exists error
When I started running sudo snapper -c root create-config / I ran into the
following error.
Creating config failed (creating btrfs subvolume .snapshots failed since it already exists).
remove existing snapshots
sudo umount /.snapshots
sudo rm -r /.snapshots
configure snapper
sudo snapper -c root create-config /
sudo snapper -c home create-config /home
btrfs subvolumes
sudo btrfs subvolume list /
sudo btrfs subvolume delete /.snapshots
sudo mkdir /.snapshots
# you might not see snapshots mounted yet
lsblk
if you check fstab you will see an entry for it #
cat /etc/fstab
mount it #
sudo mount -a
now you should see /.snapshots mounted #
lsblk
You should now see .snapshots in mountpoints.
Setting the default to @
so that you can boot into snapper snapshots
sudo btrfs subvol get-default /
sudo btrfs subvol list /
sudo btrfs subvol set-default 256 /
sudo btrfs subvol get-default /
## ID 256 gen 105268 top level 5 path @
snapper ls
sudo snapper ls
leaving off for now
