Why I screwed up my NetBSD system?
Yesterday I think I did something weird. I was running NetBSD 10.99 in
my raspberrypi Zero W.
I decided to do an upgrade to NetBSD 10-RC1 using sysupgrade utility. I
configured sysupgrade configuration file to download the sets from:
# sysupgrade fetch
I downloaded the sets.
As there is no automated way of upgrading dtb files, firmware and
kernel, I downloaded this:
I gunziped and vndconfig the image and mounted the MSDOS partition just
to extract the kernel, firmware and rest of stuff, and I put everything
in /boot. I did someting like cp -a * /boot. I inspected /boot directory
and everything apeared to be fine in place.
# sysupgrade kernel (I think it puts a kernel in / but raspberry pi does
not use that.
# sysupgrade modules
System rebooted from the RC1 kernel but I could not access the RPI from
ssh anymore, and I connected a TV set to see what happened and rebooted
again. System started but wpasupplicant sent an error, something like
failed a system call. I could not make the network work.
# sysupgrade sets
Sets where untared ok in place.
# sysupgrade etcupdate
just fine if I recalled correctly.
# sysupgrade postinstall
Many errors that I do not recall.
reboot command did not work, shutdown -p now did not work. I did
/rescue/reboot and paniced.
I rebooted the system removing power supply. The kernel started and
showed the usual booting testing drivers. It stopped with init process
paniced and kernel debug console appeared.
I broke every think and could not know how to fix it.
I extracted SD card and mounted in other computer. I think there were
many "core dump" files in /
I copyied useful files (etc, var, home, root, just important things) in
my Intel Nuc 10-RC1 NetBSD system and installed a fresh 10-RC1 system
into the SD. Now raspberrypi it is working fine in NetBSD 10RC1 after
What was my mistake? Sorry for the lack of detail but is what I can
recall from my poor memory. Just want to know what I did wrong and never
do it in the future.
Thanks so much.
