Re: flashdist-20061112 with openbsd 4.1 - SOLVED
Thank you. This helped me to figure out that installboot was clobbering
the MBR on the vnd images because of the type in the disklabel.
After reviewing arch/i386/stand/installboot/installboot.c I realized
that installboot assumes any vnd device is the same as a floppy and just
starts writing the boot blocks at the first block. This assumption
makes sense for using installboot to create, say, OpenBSD boot floppies.
For any disklabel that has a type other than vnd or floppy, installboot
lseek()s past the MBR before it writes. So, just adding echo type: ESDI $T
is sufficient to make installboot behave properly with vnd images destined
for non-floppy media.
