Oh, so that must answers the question "Is it a keyword, or the actual
name of executable file to run?" Fair enough.
One hack which might work for you:
Move /usr/bin/pygrub sideways and create /usr/bin/pygrub as a shell
script with a correct shebang line.
Have that shell script choose between the sideways pygrub in the usual
case, passing "$@" to it, or xenpvnetboot based on some specific
indication. This also gives you the ability to correctly mutate the
command line options passed to xenpvnetboot. (Because of the above
restriction, on a XenServer system pygrub and eliloader must accept
identical command line arguments, meaning that we are somewhat different
from any upstream version)
I frequently use the above shell script trick while developing, for
doing things such as wrapping valgrind/strace around sub components.
Nice trick!
I'll check what environment pygrub receive and try to find a way to tell
it to run the original loader or give the correct values to xenpvnetboot
or whatever.
Too bad it won't work "off the shelf", but I see it's just matter of time.
Thank you.
