以前は、boot.fs が 一つだったので、dd で
dd if=boot.fs of=/dev/rsd0c bs=64kのように、書いておけば、いつでも起動出来たのだけれど、 それが二枚になって、出来なくなってしまったので、 それの代替手段である。
vi /etc/disktab disklabel -w -r /dev/rsd1c 40M mydisk disklabel sd1 newfs /dev/rsd1a mount /dev/sd1a /mnt cd /mnt cp /net/quick/export/current-ts/20020819r/binary/kernel/netbsd.GENERIC_MD.gz 20020819r.gz cp /net/quick/export/current-ts/20020819d/usr/mdec/ofwboot . ln 20020819r.gz netbsd.gz cd /usr/mdec umount /mnt installboot -v -t ffs /dev/rsd1a bootxx /ofwboot/etc/disktab

installboot
や /usr/mdec
については 1.6 から変っているので、環境が違う時は、
このままでは出来ないかも知れないが考え方は同じ。
