Cool, OK now I logged in as root, ran /usr/sbin/ybin
Seemed to take, cause there was HD access, then a new prompt.
I rebooted, and did not get a linux boot either with a simple reboot or with
an Open Firmware (option key) restart.
OK, I edited /etc/yaboot.conf (there were some errors on the partitions
recorded there). Restarted, still the same; restarted with the CD and ran
/usr/sbin/ybin and I got:
hcopy: "/tmp/ofboot.Sa5K7U": read-only file system
ybin: An error occurred while writing to /dev/hda15
In addition, even after changing yaboot.conf to "defaultos=linux" I have now
graduated to a reboot which produces first a blue folder then the MacFace
blue folder, then a boot into OS9.2.1.
So I continue to *only* be able to boot linux if I have the CD in and hold
down "c"
BTW, I'm assuming in yaboot.conf that the "boot" partition looked for in the
top of the file is the 10MB "bootstrap" volume (/hda15) created in the
installer and the "root" partition is root, at /hda14
Thanks
