I'm using UBIFS in my "hybrid" OM2008 (still :P) based distro for some
months; In my case I had to backport the kernel patches too, then I used
an SD installation of SHR to flash the generated ubi image in my nand
via ubiformat (which is a LOT faster than using dfu-util; with it
flashing an ubi image takes just few minutes).

I've still some issues on creating a correct ubi image by the way; the
hardware parameters returned by ubinfo (in a distro running a kernel >=
2.6.30) doesn't seem to be correct, and I've to force the page size

Coming back on the Mickey's question, however, I've to say that I've
noticed a nice speed improvement on booting and on running many

PS: It works well using uBoot too with adding these cmdline parameters:
    rootfstype=ubifs ubi.mtd=6,2048 root=ubi0:rootfs
