Ok, my bad, I should've tested this with MicroOS since the beginning, I can
reproduce it with snapshot 20240520.

There was not any change in dracut that could affect this between the version
shipped with SL Micro and the latest Factory version, and the arguments in
dracut look ok:

> May 22 13:05:43 localhost dracut-cmdline[233]: dracut-059+suse.588.g528264be-1.1
> May 22 13:05:43 localhost dracut-cmdline[233]: Using kernel command line parameters:  ... rootfstype=btrfs rootflags=ro,compress=zstd:1 ...

Also, `findmnt` reports the right options on the running system:

> localhost:~ # findmnt --fstab -e -v -n -o 'OPTIONS' --target /
ro,compress=zstd:1

But, /proc/self/mountinfo trims the value of compress=... So, I guess this
should be an issue with kernel 6.9.1-1-default (it works with
6.4.0-17-default).
