ybin userland interface for specifying bootonce
Add an option to ybin called "--bootonce" that takes exactly one
argument, the label of the kernel to boot exactly once, on next reboot.
Do some sanity checking. Grep through the yaboot config file to make
sure that label=WHATEVER exists somewhere, bail if not. Try to prune
out comment lines. Perhaps this might be implemented better. It worked
will in my testing, though.
Set the boot-once OF environment variable to the --bootonce value. Due
to the previously mentioned nvsetenv bug, this will fail silently if
you're trying to set boot-once on a system where boot-once doesn't
already exist in nvram. Thus, immediately after doing the set, try and
read it back out of nvsetenv and make sure it landed there. Bail if
not.

yaboot menu user interface
This patch allows for denoting a kernel label as a "boot-once" label
when printing the menu of labels.
The label flagged as default is marked with an asterisk (*). If a label
matches the global bootoncelabel, I'm marking it with an ampersand (&).
I'm ambivalent about the symbol used here, or even if it is. But I
found this bit useful when debugging and testing the functionality, and
it's trivial to add cleanly. I chose ampersand because it's immediately
left of the asterisk on my keyboard.

read boot-once, zero out, set bootoncelabel as default
This patch reads the boot-once environment variable from Open Firmware
and stores in a global variable, "bootoncelabel".
It then unconditionally zeros out the boot-once environment variable.
*** Note that according to 1275, setprop will create a specified
environment variable if it doesn't already exist. A bug in nvsetenv
causes it to fail silently if you try to set an OF environment variable
that does not already exist. However, simply booting a system running a
yaboot with this patch set compiled in will in fact create the boot-once
environment variable, which nvsetenv can later set and reset.

Certain levels of IBM firmware will allow the system to boot from an
iscsi target. System OFW accomplishes this by setting up a virtual
disk device with parameters. These parameters, when passed back to
OFW by yaboot, directs the FW to use virtual device over the ethernet
port that will then access iscsi target as a block device. This patch
extracts those parameters from the property of the virtual device and
passes them back to OFW to indicate the kernel is to be retrieved via
the iscsi protocol.
