Oh, just 2M. It doesn't contain anything but copies of /bin/bash.

I basically just made a crash-tester script that corrupts a dummy
filesystem on purpose. But it seems that it might be partly my own
fault for not protecting the bits in the filesystem image that say
"oh, proceed on error". But I do have a feeling that the filesystem
should not be able to say this in the first place. Because those bits
can be corrupted legitimately in other ways too!

Is there a way to override the

"Errors behavior: Continue"

information which is present in the filesystem?
