The filesystem options declared for the root file system are apparently
ignored. This happens for a btrfs root filesystem on a LUKS volume.


Exerpt from '/etc/config.scm":

/dev/mapper/cryptroot /gnu/store btrfs
  ro,relatime,ssd,space_cache,subvolid=5,subvol=/gnu/store

Here we see that the options 'autodefrag' and 'compress=lzo' have
disappeared on the root filesystem. Maybe it has something to do with
the new '/gnu/store' subvolume that appeared?

Hello Guillaume,

Guillaume Le Vaillant <glv <at> posteo.net> skribis:

It looks great to me.

Applied, thanks!
