The grep and sort line in bin/bootsetup is where the bug is as far as I can see ( /sys/lib/dist/pc/inst/bootsetup:40 ).
			grep -v '(^\[)|menuitem|adisk|bootfile|bootdisk|bootargs|nobootprompt|mouseport|vgasize|monitor|cdboot' |

Only one argument given to grep so it read from stdin instead of a plan9.ini file. I tried to paste in the file I thought was the right, but I had to edit plan9.ini before rebooting anyway. Maybe it's because sort has the argument that grep is missing.

That's why I'm wondering if they're still needed.

Back in November, there where problems with the then recent
plan9.iso's (see thread "Problems Booting Plan9 CD", started on Nov 1,
2007). So the third boot option was added (see thread "Suggestion:
Programming Tutorial for /sys/doc", also started on Nov 1, 2007,
especially the second post by Geoff).

The problem I had before the third menu option was introduced, was
that the booting process would fail already before it reached the
menu.
After the third menu option was added however, the iso's have been
working fine for me: the menu is reached, and all of the options
(including the "debug 9load" one) work. Hence, I have the feeling that
removing the third menu option again would be no problem. I'd be happy
to test an image without the third menu option to check if my feeling
is right.

Greetings, Sander.
