Manjaro 21.0 Full Install with btrfs + snapper + grub-btrfs

Hi all, in this video i will show how to install Manjaro 21.0 with btrfs + snapper + grub-btrfs.

btrfs is a modern copy on write (CoW) filesystem for Linux.

Snapper is a tool created by openSUSE’s Arvin Schnell that helps with managing snapshots of Btrfs subvolumes.

grub-btrfs include btrfs snapshots in GRUB boot options.

I hope you enjoy!

And change line 16 to:

btrfs: noatime,space_cache,autodefrag,compress=zstd  

Change line 44 to:

btrfs: ssd,noatime,compress=zstd,commit=120,autodefrag,space_cache  


$ sudo [vim|nano] /usr/share/calamares/modules/mount.conf

Append this lines to the end of file:
