[Nut-upsdev] mdadm --readonly which device in halt?

[David Mathog]

Answer from Stuart Gathman on the linux-lvm list:  For a root (or other)
file system on LVM no special /etc/init.d/halt modification is needed.
The volume is remounted read-only in the existing /etc/init.d/halt script
and the LVM metadata is apparently not volatile, unless by pure bad luck
you happened to be rearranging the logical volumes when the power failed.
