>Description:
Trying to test drive sysinst on a NetBSD installation on a
Macintosh IIcx, I found that it gets the native Macintosh partition
table wrong and, if you let it have its way, trashes non-NetBSD partitions.
First try with one disk:
scsibus0 at ncrscsi0: 8 targets, 8 luns per target
sd0 at scsibus0 targ 0 lun 0: <DEC, DSP3107LS, 440C> SCSI2 0/direct fixed
sd0: 1021MB, 3117 cyl, 8 head, 83 sec, 512 bytes/sect x 2091144 sectors
sysinst said
Edit Disk Partition Map: The Map on the disk has been scanned for all
user-level partitions, but only those usable by NetBSD are displayed.
The partition table currently looks like:
Part size offset fstype use mount point (name)
sd0d 119476 96 HFS MacOS (Schnurrrps)
sd0a 60806 119572 4.2BSD Root /
sd0b 158490 180378 4.2BSD swap
sd0g 616350 338868 4.2BSD Usr
sd0d 422640 955218 4.2BSD Usr
sd0e 193732 1377858 4.2BSD Usr
sd0f 519554 1571590 4.2BSD Usr
(note that 'd' shows up twice!)
but the disklabel output was
8 partitions:
# size offset fstype [fsize bsize cpg]
a: 60806 119572 4.2BSD 0 0 0 # (Cyl. 180*- 271*)
b: 158490 180378 swap # (Cyl. 271*- 510*)
c: 2091144 0 unused 0 0 # (Cyl. 0 - 3149*)
d: 119476 96 HFS # (Cyl. 0*- 180*)
e: 422640 955218 4.2BSD 0 0 0 # (Cyl. 1438*- 2075*)
f: 193732 1377858 4.2BSD 0 0 0 # (Cyl. 2075*- 2366*)
g: 616350 338868 4.2BSD 0 0 0 # (Cyl. 510*- 1438*)
h: 519554 1571590 4.2BSD 0 0 0 # (Cyl. 2366*- 3149*)
When I proceeded, sysinst said something to the effect "Partition f
extends beyond end of disk". At that point I decided to play it safe
and try the actual install on a disposable disk.
scsibus0 at ncrscsi0: 8 targets, 8 luns per target
sd0 at scsibus0 targ 0 lun 0: <DEC, DSP3107LS, 440C> SCSI2 0/direct fixed
sd0: 1021MB, 3117 cyl, 8 head, 83 sec, 512 bytes/sect x 2091144 sectors
sd1 at scsibus0 targ 2 lun 0: <QUANTUM, LP240S GM240S01X, 6.3> \
SCSI2 0/direct fixed
sd1: 234MB, 1818 cyl, 4 head, 65 sec, 512 bytes/sect x 479350 sectors
The disklabel showed the layout as
3 partitions:
# size offset fstype [fsize bsize cpg]
a: 50856 96 HFS # (Cyl. 0*- 195*)
b: 428398 50952 HFS # (Cyl. 195*- 1843*)
c: 479350 0 unused 0 0 # (Cyl. 0 - 1843*)
which I split in sysinst like
Edit Disk Partition Map: The Map on the disk has been scanned for all
user-level partitions, but only those usable by NetBSD are displayed.
The partition table currently looks like:
Part size offset fstype use mount point (name)
sd1d 50856 96 HFS MacOS (Mac HD 2)
sd1a 60000 50952 4.2BSD Root /
sd1b 61728 110952 4.2BSD swap
sd1g 220000 172680 4.2BSD Usr /usr
sd1d 80000 392680 4.2BSD Usr /home
-- note again that 'd' is mapped to the HFS partition as well as the /home
partition. When I proceeded I got
Setting up the Disk Partition Map ...
[...]
Status: Finished
Command: /sbin/newfs /dev/rsd1a
[...]
Status: Failed
Command: /sbin/newfs /dev/rsd1d
Press any key to continue
i.e., sysinst was actually trying to newfs the HFS partition, and
after a reboot to MacOS I found indeed that the first (HFS) partition
was trashed.
Additional minor quirk: When booting the install kernel to the raster console,
the cursor keys do not work.
>How-To-Repeat:
Try to install NetBSD on a Macintosh by using sysinst. Have it trash
your boot disk, reinstall System 7.0.1 or whatever there was before, and
curse the i386 yuckage compatibility that apparently has leaked through.
>Fix:
None, sorry - I am not really familiar with sysinst. I haven't exactly
grown to like it on i386...
