Memo to myself: backup!
In a failed attempt at editing the disklabel, I eventually deleted it
and obviously I could not boot again. I did not save the disklabel
geometry before hand (Yes, I know...), so I booted from the install
disk and tried to recreate the information by hand. So I did:
# disklabel -i ld0
I selected 10GB for the whole disk and 9.5 GB for the NetBSD
partition, because I had a 500MB swap partition, saved, crossed
fingers, rebooted and:

So, at this point I wonder if there is anything I can do. I haven't
played with NetBSD for a while and disklabel has always been a problem
for me.
I wonder if I can at the very least recover some data of the old disk
and dump it somewhere else. It's a qemu disk, so it's no big deal
creating one more. The problem is that I had a lot of data.
This is what I see from the recovery shell:
Any help will be appreciated.
