I'm generally ok with the patchset. The only thing I'm thinking of is if busybox mount
supports PARTUUID syntax in fstab. Can you check this, please?

his reproducible builds concern.

Can you rebase your patchset on top of current master?
It would be also nice to get this functionality covered by tests.
