FWIW I tend to use ext4 without journal. And since the questions have
come up in this thread...

 - why no journal?
   It takes up space; it adds complexity. And it won't
   be there when you most need it anyway -- i.e. when
   GRUB tries to access it.
   But these are my two cent and mine alone. You can
   have 'em if you don't complain :-)

The other tendency here "ext2 is very old, don't use it" -- hm. I think
this is exaggerated. Ext2 is fine and stable for this use, and I don't
see any downsides (yet). Perhaps the day file system code gets significant
strengthening against malformed FS images, and *if* ext2 is left behind
in that effort... but it seems we're not there yet.
