Perhaps this is valid only for older versions of unionfs. I am using
unionfs mounted on /var that is composed of a tmpfs mounted on
/mnt/tmpfs, and the original /var that is on the flash (containing
only a few important files and directories that must be preserved
across reboots, like /var/lib/dpkg).
$ mount | grep "unionfs"
unionfs on /var type unionfs (rw,relatime,dirs=/mnt/tmpfs=rw:/var=rw)

With UnionFS-2.5.11 i could merge /var/cache/etc=rw and /etc=ro at
/etc. But evidently i have no real world testing going on here. Is
there any specific test case i should try to confirm this?
I think I was remembering it wrong. I think my actual problem was
because I was trying to put the union on "/", and so the source of the
union was *under* the mount-point. And who knows, this might work now too.
