NetBSD/i386
>Description:

On my i386 machine I have a dual boot install with NetBSD and Linux.
NetBSD is on /dev/sd0a
Linux is on /dev/sd0e
The swap partition is "shared" on /dev/sd0f.
There's no /dev/sd0b

NetBSD/i386 is fresh installed.

At boot time, swapctl -A -t noblk  enables the swap,
vmstat and top report the available swap space correctly.

savecore says '/dev/sd0b: Device not configured'

swapctl -z says 'dump device is sd0b'

Workaround/Fix:

Change the entry in /etc/fstab:

-/dev/sd0f              none    swap    sw               0 0
+/dev/sd0f              none    swap    sw,dp            0 0

and swapctl -z says 'dump device is sd0f'
and savecore works as expected.

>How-To-Repeat:


>Fix:

sysinst should add the 'dp' switch in /etc/fstab when dump device
is redefined.
