savecore setup

I have 2 disks

# disklabel -rt sd1

kernel config contains:
    config          netbsd  root on sd2a type ffs

/etc/fstab contains:
    /dev/sd2a / ffs rw,softdep 1 1
    /dev/sd1b none swap sw,dp 0 0

Now, I managed to get a coredump written I assume to sd1b.

# swapctl -zn
dump device is sd1b

The problem is, how can I read it?

# savecore -vn
dumplo = 11238912 (21951 * 512)
savecore: /dev/rsd2b: Device not configured

Sure sd2b isn't configured... Why is savecore looking there? Simply
partition b of the same disk root is on, even though there is no
such partition?

It may be a bit late now too:

# swapctl -lk
Device      1K-blocks     Used    Avail Capacity  Priority
/dev/sd1b     2098040        0  2098040     0%    0

This is on NetBSD-4.99.55/i386 of Mar 3 11:19 GMT.

Cheers,
