Should be FAKEROOT, not FAKE_ROOT (if we validate the whole proposal
this patch is doing).

Well, the conventional way would be to have those directories created
by packages (and they can use the <pkg>_PERMISSIONS mechanism to get
proper ownership or permissions). Or, if they really don't belong to
any package, create them in the post build script, and have a device
table assign the permission and ownership.
