Can I change the location of BTRFS snapshots. I installed CachyOS, and it automatically setup BTRFS subvols.
This is the layout ๐

According to Arch wiki https://wiki.archlinux.org/title/Snapper#Creating_a_new_configuration
Create a subvolume at /path/to/subvolume/.snapshots where future snapshots for this configuration will be stored. A snapshot's path is /path/to/subvolume/.snapshots/#/snapshot, where # is the snapshot number.
From which I understand that if I created a snap of /home (@home), it will save in /home/.snapshots (@home/.snapshots).
So, CachyOS configured to save snaps to separate subvol.
But, what I want to do is, Instead of just saving it in separate subvol, i want snaps to be saved on different btrfs partition. Maybe @home/.snapshots but on different partition.
Is that possible ?
