Installed Arch Phosh On Btrfs Root

[kaida]

I successfully succeeded in having My Root filesystem use Btrfs , next step is to play with snapper


Will soon post a guide on how to , for those wanting to know / try

but basically goes as follow :

Started by flashing an image of arch phosh

backed up the filesystem in a tar

setting up an ext4 boot partition and the Btrfs partition and subvolumes

extracting the fs from the tar back into the mounted btrfs layout

added some arguments to boot.txt inside /boot ( extraargs=rootflags=subvol=@ rootfstype=btrfs ) to the setenv line

regenerated a boot.scr with mkimage

fixed fstab with uuid
