22 Correct me if I'm wrong here, it used to be that grub, the original
23 version not the current bloated one, had to have ext2.  At the time,
24 that was *the* file system.  If I recall correctly, a ext4 file system
25 can be *read* the same as ext2.  The difference is the journal.  So,
26 when booting, grub etc is only reading /boot and it shouldn't matter if
27 it is ext2, ext3 or ext4.  It's only when being written to that it
28 matters.  Am I recalling that right? 
30 Another one of those times where Linux provides a ton of options.  :/
