RE: "Using Disk: 0 Partition: 3" problem

[Vazquez Javier <j_(_dot_)_vazquez_(_at_)_nzz_(_dot_)_ch>]

i had this problems some months ago and i only had it with machines that had
formerly installed linux --> lilo! if you've installed linux on that machine
IMHO you can't just install openbsd over it without deinstalling lilo from
your mbr first ("lilo -U" or something like that?).

as far as i see you allready wiped linux off your disk, maybe you should
take a look at your disk manufactureres website and find a tool to
lowlevel-format your disk.

Fiddling around a bit more I found the following:
This machine has the boot.conf error 20 problem I explained in a
previous post in this thread, some other machines I admin exhibit the
same problem.
Now, when I compile a new kernel and then mv it into place with:
mv /bsd /bsd.old
mv ./bsd /bsd
it fails to boot. Entering an ls at the boot> prompt either doesn't show
the file or says it's size 0. Either way it fails to boot that kernel.

And now for the twist.

If I compile the same kernel, same options on the same machine but copy
it instead of moving it it works:
cp /bsd /bsd.old
cp ./bsd /bsd

boot> ls now shows the correct size, it boots without any problems.

Any idea why this happens?
