This is what he wants, a workaround so he can fsck. However, the above
command (on version 1.2-WIP) just gives me:

Invalid filesystem option set: ^FEATURE_C4

Maybe he should just edit the source so it doesn't set the superblock flag
for now.

BTW, there doesn't seem to be a --version command in tune2fs.
