This is still potentially risky as the readonly mount may read inconsistent
data from the disk. It shouldn't damage the on-disk data but there may be
errors from the filesystem driver. I guess it's possible that it could cause
more severe errors too but that would rather depend on the particular
filesystem, the particular circumstances, etc.
All the same, it's something I personally wouldn't want to risk doing from
dom0 on a production machine - just in case.
Cheers,
