Ubifs is built on the Ubi layer, which handles resizing (and does so in
the face of flash errors).

http://www.linux-mtd.infradead.org/doc/ubi.html#L_autoresize

Then again, since ubifs mounts quickly, the largest reason for
partitioning we've had (to reduce boot time) evaporates.  There may be
other reasons to want partitioning, given dynamic resizing a'la lvm,
however.

If we go to non-bare flash, of course, other solutions will have to be
found.
