Hello Michael,

thanks for your reply.

As discussed on the phone already, I don't think dracut is the root cause here, since
the mount options are fine on systems running Core Update 168. Some change in Core Update
169 caused this issue.

No, it is the other way round. Silly me screwed up the diff. :-/

Anyway, commit 54bd60b67b477e5d5814293a74086dff1c21ac69 addresses all of them except for
/dev. I searched and was unable to find any component where /dev is (re)mounted in the way
it is shown in the output of "mount".

Do you have any ideas?

Thanks, and best regards,
Peter Müller
