Yes, it would be nice, and I wish it'd been done that way.  I'm hoping
it will be once it's in the kernel.  I liked how I didn't have to do
anything for the upgrade to happen, but I'd probably like it more if
this was something you had to do with a userland tool or a specific
kernel boot/mount option.

Not sure.  I got 2.6.13 to work without much trouble, but I wasn't using
the full MM patch, just the reiser4-specific parts.
