hang after reboot - fs read only

[Riccardo Mottola]

Hi,

I was upgradeing Hurd + Debian on real hardware (ThinkPad) and I left it
running. I found out the system rebooted itself, so i don't know how far
it progressed.

If I reboot, boot doesn't finish
I also tried recovery mode, but it does not complete - filesystem not
unmounted cleanly, but then it finishes:

INIT: No inittab.d directory found
ext2fs: part:1:device:hd0: warning: FILESYSTEM NOT UNMOUNTED CLEANLY;
PLEASE fsck
ext2fs: ../../libdiskfs/node-drop.c:45 disk2_drop_node: Assertion
'!diskfs_readonly' failed
INIT: cannot execute "/etc/init.d/rcS"

what could it be? I suppose it should be readonly to boot and use
fsck... that's the point of recovery mode.

also, how can I fix it? I fear I need an external boot disk and check
the drive, but it could be that soemthing is inconsistent?
