>Description:
After upgrading a FFSv2 NetBSD 3.0 system to NetBSD 3.0.1 the system doesn't boot. Before upgrading:
--

NetBSD MBR boot                                           

NetBSD/i386 ffsv2 Primary Bootstrap

Press return to boot now, any other key for boot menu     
booting hd0a:netbsd - starting in 3

After upgrading:
--

NetBSD MBR boot                             

NetBSD/i386 ffsv1 Primary Bootstrap         
Boot failed (errno  2): Can't open /boot.   

-
I suspect the new "ffsv1" primary bootstrap instead of "ffsv2" is causing the problem. I don't think the NetBSD install program checked the partition type and just assumed it was a FFSv1 partition.

>How-To-Repeat:
Install a NetBSD 3.0 i386 system.

Upgrade it to NetBSD 3.0.1 and reboot the system.

Note this was all attempted on Virtual PC 2004, not on real hardware.

>Fix:
Don't upgrade a bootable FFSv2 partition?
