The state of Debian GNU/Hurd is still painful.

So yesterday, after I reported to you about the SSH issue, the OS was
hung on the sshd process. It couldn't even terminate the process. So I
had to reset the box.

Upon reset, as expected, I ran into file system inconsistency issue. So
now I had an install that was not bootable.

The tricky part is on how to debug such states. At that point, when it
is in boot-up, I do not have a (emergency) shell. The login program
just loops and respawns. So, I've not found a way to debug these
problems. My only option is to revert back to my good working snapshot.

I've seen that happen before, where the login program just loops indefinitely. To fix it, and avoid reverting to a snapshot, I simply mount the qemu image as a regular partition on the host system and then fsck it. This allows me to boot the Hurd again without any issues.


So do you have any advise on how to root cause these ?
