This is a clone of:
https://github.com/yast/yast-update/issues/197

due to no responses in there.

In yast-update/src/modules/RootPart.rb, Line 41 in b3e78e0 there is:
 NORECOVERY_FS = [:btrfs, :ext3, :ext4, :xfs].freeze 

norecovery was deprecated in torvalds/linux@74ef001 (5.9) and finally removed
in torvalds/linux@a1912f7 (6.8). Due to that, btrfs cannot be probed by yast
now:

btrfs: Unknown parameter norecovery

It used to warn between 5.9 and 6.8:

'nologreplay' is deprecated, use 'rescue=nologreplay' instead

Yast should adopt, but I don't know how to do it in a generic way...
