I thought I'd give an update on this. I have managed to
boot to a shell in single-user mode. I don't know what
was going wrong before, but I added some debugging output
to /bin/sh and then everything worked. I suspect it was
simply remaking the object files for /bin/sh that fixed
the problem.
The problem I am having now is mounting the memory disk
read-write.
My /etc/fstab looks like this:
/dev/md0a / ffs rw 1 1
The boot messages indicate I have the correct device:
md0: internal 2048 KB image area
root on md0a dumps on md0b
root file system type: ffs
It seems I also have the device nodes:
# ls -l /dev/md0*
brw-r----- 2 root 0 17, 0 Apr 18 12:15 /dev/md0a
brw-r----- 1 root 0 17, 3 Apr 18 12:15 /dev/md0d
But when I try to mount the memory disk rw:
# mount -u -w /dev/md0a /
mount: cannot open `/dev/md0a': Device not configured
And using /etc/fstab:
# mount -ua
mount_ffs: /dev/md0a on /: specified device does not match
mounted device
I have tried this both with a normal kernel:
# mount
root_device on / type ffs (read-only, local)
And also one where I substituted the "root_device"
string
in the ffs code to give:
# mount
/dev/md0a on / type ffs (read-only, local)
Similar errors either way.
