o   ext3 = ext2 + journaling
o   /boot would NOT be mounted after boot-up
o   the journal is never used (since it's not mounted)
o   and just wastes space and no benefit
o   (this I'm not particularly sure about the exact %)
     journaling takes another 60% space requirement

Oh, I do have a 'special boot partition' and it boots up all my OS, 
doesn't have any kernel, size of 1.2 MB, modify about once every year 
and yes, in ext2.

But as I said, you can keep yours in ext4, why not use btrfs (supported 
in natty) for example?
