System: NetBSD 9.0 (RAMDISK) #0: Fri Feb 14 00:06:28 UTC 2020 mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/hp300/compile/RAMDISK
Architecture: m68k
Machine: hp300
>Description:
When checking PR install/55201 (9.0 hp300 sysinst cannot find root)
I noticed that sysinst add a swap using the target /dev/sd0b disk
but it was not released after error.
Then the second try of upgrade silently fails.

NetBSD/hp300 9.0
This menu-driven tool is designed to help you install NetBSD to a hard disk,
or upgrade an existing NetBSD system, with a minimum of work.
In the following menus type the reference letter (a, b, c, ...) to select an
item, or type CTRL+N/CTRL+P to select the next/previous item.
The arrow keys and Page-up/Page-down may also work.
Activate the current selection from the menu by typing the enter key.
If your machine has 4MB or less, sysinst will not operate correctly.
Thank you for using NetBSD!

Ok, let's upgrade NetBSD on your hard disk. As always, this will change
information on your hard disk. You should have made a full backup before
this procedure! Do you really want to upgrade NetBSD? (This is your last
warning before this procedure starts modifying your disks.)
Yes or no?
a: No
>b: Yes
---
On which disk do you want to upgrade NetBSD?
Available disks
a: current system
>b: sd0 (2.2G)
x: Exit

When I chose "b" on this "On which disk" prompt, sysinst silently got
the initial sysinst menu:

You have chosen to install NetBSD on your hard disk. This will change
information on your hard disk. You should have made a full backup before
this procedure! This procedure will do the following things:
a) Partition your disk
b) Create new BSD file systems
c) Load and install distribution sets
d) Some initial system configuration
(After you enter the partition information but before your disk is changed,
you will have the opportunity to quit this procedure.)
Shall we continue?
Yes or no?
a: No
>b: Yes

On which disk do you want to install NetBSD?
Available disks
>a: sd0 (2.2G)
b: Extended partitioning
x: Exit
---
The disk that you selected has a swap partition that may currently be in use
if your system is low on memory. Because you are going to repartition this
disk, this swap partition will be disabled now. Please beware that this
might lead to out of swap errors. Should you get such an error, please
restart the system and try again.

Actually /dev/sd0b is in swapctl:

[1] + Suspended sysinst
# swapctl -l
Device 1K-blocks Used Avail Capacity Priority
/dev/sd0b 131200 0 131200 0% 0
#

Maybe that's the reason silent failure on the second try?
>How-To-Repeat:
See above.
>Fix:
Maybe it's better to call "swapctl -d" on any errors during installation?
(at least silent failure is a bad thing)
