thanks for clarifying.

fwiw, this is an issue/challenge only if trying to use pre-formatted
LVMs created in the Dom0 _as_ the drives in the DomU. i.e., passing
the disks as phy:.../xvda1.  for that to work -- without other hoops
to jump through -- the fstab needs to be there.

i _do_ understand that i can pre-populate those formatted LVMs with
the typical root dir tree beforehand, but, when trying to keep DomU's
"thin" there's often too much copied.  one option is to keep a
minimal-spin around, and copy from _that_.  just more work that
ideally needs to be done.

of course, passing the LVMs in as physical devices, i.e. as
phy:.../xvda, and letting autoyast create/format subpartitions, e/g/
/dev/xvda1, works perfectly.

like you said, perhaps a future enhancement ...

thanks!
