I doubt they're actually fascists or racists, but they certainly seem like the kind of people to be sympathetic to fascists, racists and/or KKK members.

Fortunately, subsequent runs of fsck ended up likewise, so I was able to get a core dump by re-executing fsck while being inside a TMPFS-backed directory. (On the other hand, unfortunately, fsck was never able to replay the journal.) Furthermore, I saved the .sujournal file, but saving the contents of the whole filesystem was beyond my resources. (It would have been adequate to use a tool that collected (only) the blocks that fsck read before segfaulting (thus constructing a small test case), but no such tool was at hand.)

This routine is prompted by (1) personal experiences of files getting lost or truncated to 0 length, and (2) past reports of disasterous behaviors involving soft updates, such as untouched (read-only) files getting lost; "lost" means not even relinked to /lost+found or anything. And wouldn't ya know it, fsck did ask whether to remove something that had an unambiguously large size (to be exact, IIRC: "DUP ... REMOVE?", whatever that means). That's it, either (a) remove the file, or (b) stay dirty; take it or leave it. It's not like there was some 3rd option to relink the file to /lost+found. After "fsck -y", the file disappeared without a trace. GAAAAAAAAAY.
