System: NetBSD 9.0 (INSTALL) #0: Fri Feb 14 00:06:28 UTC 2020 mkrepro%mkrepro.NetBSD.org@localhost:/usr/src/sys/arch/luna68k/compile/INSTALL
Architecture: m68k
Machine: luna68k
>Description:
LUNA machines require an old 4.4BSD derived FFS partition to
load bootstrap loader on its firmware so prior sysinst for
NetBSD/luna68k creates a boot partition on partition d:

On NetBSD/luna68k 9.0 there is no loger "PART_BOOT" like options
in md.h:

In "Set sizes of NetBSD partitions" sysinst seems to try create
the boot partition at the top of the disk:
---
You can now change the sizes for the system partitions. The default is to
allocate all the space to the root file system. However, you may wish to
have separate /usr (additional system files), /var (log files etc) or /home
(users' home directories) file systems.
Free space will be added to the partition marked with a '+'.
Size (sec) Filesystem
----------------------------------- - --------------------
>a: 16384 (Other: FFS)
b: 131072 (232442) + /
c: 0 <swap>
d: 0 /tmp (mfs)
e: 0 /usr
f: 0 /var
----------------------------------- - --------------------
h: Add a user defined partition
i: Clone external partition(s)
j: Change input units (sectors/cylinders/MB/GB)
x: Go on. Free space 101370 sec.
---
and no swap space is allocated by default.
After that, the disklabel editor shows:
---
We now have your disklabel partitions for sd0 below. This is your last
chance to change them.
Flags: (I)nstall, (N)ewfs. Total size: 121M, free: 512B
Start (sec) End (sec) Size (sec) FS type Flag Filesystem
------------ ------------ ------------ -------- ---- ----------------
a: 0 16383 16384 FFS IN
b: 0 248825 248826 Whole disk
c: 16385 248825 232441 4.2BSD N /
------------ ------------ ------------ -------- ---- ----------------
e: Change input units (sectors/cylinders/MB/GB)
f: Edit name of the disk
g: Clone external partition(s)
h: Cancel
>x: Partition sizes ok
---
As shown above, partition "a" is boot,
partition "b" is whole disk (i.e. no swap),
and partition "c" is root partition.
Note there is no choise to "add a partiton" here
so no way to add a swap partition.
>How-To-Repeat:
Install NetBSD/luna68k 9.0 via sysinst.
Whole sysinst log is attached:
---
NetBSD/luna68k 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.
Thank you for using NetBSD!
NetBSD-9.0 Install System
>a: Install NetBSD to hard disk
b: Upgrade NetBSD on a hard disk
c: Re-install sets or install additional sets
d: Reboot the computer
e: Utility menu
f: Config menu
x: Exit Install System
---
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 (121M)
b: sd1 (30G)
c: Extended partitioning
x: Exit
---
You can use a simple editor to set the sizes of the NetBSD partitions, or
apply the default partition sizes and contents.
You will then be given the opportunity to change any of the partition
details.
The NetBSD (or free) part of your disk (sd0) is 121M.
A full installation requires at least 942M without X and at least 1192M if
the X sets are included.
What would you like to do?
>a: Set sizes of NetBSD partitions
b: Use default partition sizes
---
You can now change the sizes for the system partitions. The default is to
allocate all the space to the root file system. However, you may wish to
have separate /usr (additional system files), /var (log files etc) or /home
(users' home directories) file systems.
Free space will be added to the partition marked with a '+'.

>Fix:
Not sure.
src/usr.sbin/sysinst/README.md_defs says:

> whole disk.
I'm not sure what "the suggested default partitions" mean here,
but at least this is not neccesary for luna68k.
