I thought PARTUUID is for GPT only.

Perhaps so but it does seem to be there on my VirtualBox systems.  My Ubuntu host uses "root=UUID=blah" but that was't working for me at some point.  I'll dig back into it and see what I can find.

root=UUID=xxx has to be resolved by an initramfs because kernel itself cannot handle it.

There's a patchset I sent half a year ago trying to solve this problem.

This offers one solution, maybe an ugly one.

Hmm.  It seems that supporting static device paths with init-install.sh is a bit more tricky as PARTUUID is not supported and to use UUID requires a fairly heavyweight change to support initramfs.

For EFI though it seems that PARTUUID is usable.  Does it make sense to submit the patch to init-install-efi.sh separately?
