I think its actually there because ubifs wasn't around when OLPC
needed to make a decision on filesystems. UBIFS hasn't been around
that long.

No idea, but you can use a small /boot partition with jffs2 (or ext2)
which is enough to boot the kernel and then have a ubifs root file
system.

Well there's details of what experimentation was done with ubifs on
the wiki here
