[9fans] next-server dhcpd option

[Matthias Teege]

Moin,

how do I specify dhcp options like "next-server" or "option root-path"
in the Plan 9 ndb?

based on my limited understanding of what 'next-server' does.  it
seems that it wouldn't be needed because you could import and
aggregate ndb that dhcpd uses.  there are various 'sleep' and ip
ranges options for dhcpd that might help with division of
responsibilities between servers.

about 'option root-path': would bootf parameter in ndb and the
/cfg/pxe/<macaddress> (plan9.ini) be what you're looking for?  or for
a cpu, through /lib/namepsace.cpu

I have to boot some linux systems from my Plan 9 dns/dhcp/tftp server
via PXE. Pxelinux needs a tftp server which supports the tsize option
and I think the Plan 9 one doesn't do that. So my idea is to redirect
the tftp requests to another tftp server via the next-server option. But
I'm interested in any other solution.

I try to boot from an AoE target with etherboot/gpxe and on there website
[1] they use:

  filename "";
  option root-path "aoe:eN.M";

I can replace filename with bootf but don't now about root-path.

What about implementing tsize?. :-).
