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