That's not a use case. *Why* is the user using -p? The -p option is only intended to be used when called from boot scripts, where e2fsck is run in parallel. This usage, "preen mode" dates back to BSD 4.3. What it does is pretty clearly described in the man page. The user seems to be very confused with their expectation, and it's not at all clear it's a correct one. Why does the user have this expectation, and under what circumstances would they want e2fsck to abort for some fixes, and automatically fix others, *and* want a full set of messages of what was fixed? If you are running things interactively (e.g., not at boot time), having e2fsck abort for certain sets of error may end up wasting a lot of time, since then you'll have to restart the e2fsck run. Essentially, I'm asking for a complete justification for why this is a general thing that many users will want, and why it makes sense for them to want it. The fact that *some* user had some twisted expectation, and filed a Lustre bug, doesn't mean that you automatically get to have that expectation satisified in the upstream e2fsprogs sources. You need to justify why other users would want it, and how this is optimal for that particular way that people would want to run e2fsck, for some particular set of circumstances. Otherwise, some other user will have some *other* set if expectations, and file another bug with Debian or Red Hat, demanding some other random change, and this way lies madness. - Ted
