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:
On NetBSD/hp300, users have to prepare a "boot partition" to store
NetBSD/hp300 native bootloader because it's larger than 8KB reserved
by FFSv1. On NetBSD 8.0 (and 8.2) sysinst in NetBSD/hp300 RAMDISK
kernel properly prepare a boot partition with one cylinder on
new installation:
---
On which disk do you want to install NetBSD?
Available disks
>a: sd0 (34G, SEAGATE ST336754LC)
b: sd1 (34G, SEAGATE ST336754LC)
c: sd2 (34G, SEAGATE ST336754LC)
d: Extended partitioning
x: Exit
---
(note 8.2 doesn't have NOLUN quirk for the SEAGATE SCA 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 '+'.
MB Cylinders Sectors Filesystem
>a: 356 (34861) 518 730380 + /
b: 128 186 262260 swap
c: 0 0 0 /tmp (mfs)
d: 0 0 0 /usr
e: 0 0 0 /var
f: 0 0 0 /home
g: Add a user defined partition
h: Change input units (sectors/cylinders/MB)
x: Accept partition sizes. Free space 34505 MB, 4 free partitions.
---
We now have your BSD disklabel partitions as:
This is your last chance to change them.
Start MB End MB Size MB FS type Newfs Mount Mount point
--------- --------- --------- ---------- ----- ----- -----------
a: 1 34862 34861 FFSv1 Yes Yes /
b: 34863 34990 128 swap
c: 0 34990 34991 Whole disk
d: 0 0 1 Boot partition
e: 0 0 0 unused
f: Show all unused partitions
g: Change input units (sectors/cylinders/MB)
>x: Partition sizes ok
---
Note the "Boot partition" in d partition has one cylinder.
(calculated by hp300_boot_size() in src/usr.sbin/sysinst/arch/hp300/md.c)
On NetBSD/hp300 9.0, sysinst in the RAMDISK kernel no longer prepare
a boot partition:
---
On which disk do you want to install NetBSD?
Available disks
>a: sd0 (34G)
b: sd1 (19G)
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 (sd1) is 19G.
A full installation requires at least 868M without X and at least 1118M 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 '+'.
Size (sec) Filesystem
----------------------------------- - --------------------
>a: 790528 (39600224) + /
b: 262144 <swap>
c: 0 /tmp (mfs)
d: 0 /usr
e: 0 /var
----------------------------------- - --------------------
g: Add a user defined partition
h: Clone external partition(s)
i: Change input units (sectors/cylinders/MB/GB)
x: Go on. Free space 38809696 sec.
---
We now have your disklabel partitions for sd1 below. This is your last
chance to change them.
Flags: (I)nstall, (N)ewfs. Total size: 19G, free: 16K
Start (sec) End (sec) Size (sec) FS type Flag Filesystem
------------ ------------ ------------ -------- ---- ----------------
a: 0 39600223 39600224 4.2BSD IN /
b: 39600256 39862367 262112 swap
c: 0 39862367 39862368 Whole disk
------------ ------------ ------------ -------- ---- ----------------
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
---
Then installboot fails during default installation.
>How-To-Repeat:
Install to a new disk using NetBSD/hp300 9.0 RAMDISK kernel (see above).
>Fix:
No idea.
It would be great to share description about design changes
in 9.0 how each MD boot partition is prepared (PR/55058, PR/55060,
and also PR/55187 etc.) so that other maintainers who know about
rare Tier-II machines can also consider how messy MD quirks could
be handled.
Thanks,
