Sorry, I was confused and forgot about the ID_FS_UUID format blkid uses for raid parts: <https://github.com/dracutdevs/dracut/blob/master/modules.d/90mdraid/parse-md.sh#L17-L18> In my later patch, I only used the MD_UUID format with ':', because that is exposed in /dev/disk/by-id/ <https://github.com/dracutdevs/dracut/blob/master/modules.d/90mdraid/parse-md.sh#L34> To convert the ID_FS_UUID to MD_UUID, I now added a small conversion with patch: <https://github.com/dracutdevs/dracut/commit/f265cb67dc0b5d7b28952bcf4b9bee4e174c31b4> So, yeah, I will fix dracut in F28/27/29 Sorry for the confusion/trouble I caused here.
