Yes, I completely agree that the Systemimager 3.X design as you describe
is clumsy and must be reversed into 1 link per host *to be installed*,
and no links for properly working hosts.

Yes, we need the ability to configure multiple PXE boot configurations.
Besides node reinstall we're also happy to be able to PXE boot into
the Memtest86 memory-tester, see details at
    http://www.fysik.dtu.dk/CAMP/Niflheim/diagnostics.html

Yes, the pxeconfig tool "hexls" is indeed useful for listing the hex-encoded
IP-addresses in /tftpboot/pxelinux.cfg.

My conclusion: The Systemimager 3 PXE-installation tool should be redesigned
slightly so that it'll use the clever ideas of the pxeconfig package.
I would certainly opt to use pxeconfig with Systemimager 3.X !
