Hi Guix,
I'm trying to mount my btrfs root filesystem with the compress=lzo option.
Following Section 8.3 or the manual (System Configuration → File Systems, I
added (options "compress=lzo") to my file system definition. However, when I
reconfigure and reboot, it does not appear that the file system is mounted
with this option. When I mount the filesystem manually with `mount -o
compress=lzo …` it works correctly. Full operating system config below. What
am I missing?
Best,
Jack
from /proc/mounts:
```
/dev/nvme0n1p2 / btrfs rw,relatime,ssd,space_cache,subvolid=5,subvol=/ 0 0
/dev/nvme0n1p1 /boot/efi vfat
rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro
0 0
```
I forgot to mention: the gerated /etc/fstab looks correct
```
LABEL=lib-its13_nvme_btrfs / btrfs compress=lzo
LABEL=EFI /boot/efi vfat defaults
```
So that made me think that maybe the initramfs was the source of the
problem, but that too looks correct. /gnu/store/<hash>-init in the
initramfs looks fine as well:
