We could use jffs2 if we link /var/cache/apt to a tiny partition on SD.
Then while SD is in huge updates will work, if SD is removed -> no apt,
but still a runing system.
In my opinion ubifs is a great improvement: it looks faster than jffs2
and less memory consumer than jffs2.
It should be used, if possible. So I suggest to use it and to send
kernel messages and nandump to ubifs guys in order to help them.
And that's what I'm doing ;-)
Cheers
Giacomo
