Could it be console? After the hang, I re-entered recovery mode, the filesystem was still marked as clean. I forced a manual fsck and it did find an error on the ACL of /dev/console, fixed that, at the next reboot I could login.

Note: I don't recommend using VirtualBox.  It tends to implement hacks
to make simulation faster at the expense of correctness.  Things work
just fine with qemu/kvm/native.
Better for sure, I wouldn't say just fine.  The issue Riccardo
encounters here is the one we have the delay loop hack in
runsystem.sysv for :/

I'd love, far prefer native. But my two older boxen I could "dedicate" to HURD don't work. You both endured the many posts I gave here. I had a quite fine workin box, but it is low on mem... so my install attempts were done from an temporary computer on the HD and now I discovered that GRUB appears to have troubles (It did not a year or so ago). But I was uable to understand the problems, I asked on the GRUB Mailing list without replies. I also have a laptop, but there I get no network. You suggested wifi, but I don't have the tools for it installed. I'll make another GRUB attempt on the old box and find perhaps another laptop with integrated network (but also enough RAM since we are very demanding, most spare old laptops with fine supported hardware have 256MB of RAM...)

So since I wanted to tinker with GNUstep on HURD after such a long delayed, I just ordered more RAM and put VirtualBOX on my Mac. For Linux VirtualBox worked always quite fine.
If Justus speaks of a hack, it is maybe just the bug being exposed.

Since it appears tightly related with the FS (I was able to boot with one or several reboots into recovery and forcing fsck) I am clearly concerned that the shutdown is never clean, so it all adds up creating uncertainty.

Can we understand why my shutdown is not clean?
