Nifty.

A migration tool would have to juggle the potential for insufficient
space in /var for the export; or sufficient space for export but then
not importing. And then there's cleanup of otherwise dead space used
by device mapper. So possibly more than one fs resize is necessary.
I'd say probably leave things alone for upgrades, but documenting a
strategy for migrating to overlay is OK.
