I have a dnsmasq related question,though perhaps there is an iPXE
feature to more directly achieve what I would like.
I'd like a way to boot nodes in one dnsmasq dhcp-range or network to one
default iPXE menu-default option, and nodes in another dhcp-range (or
individually) to another default iPXE menu-default option.
Alternately, they could boot to different ipxe menus, though I'd like to
use the same menu (with different default options) if possible.
You can access arbitrary DHCP options in iPXE using numbered settings.
For example, you could force your DHCP server to hand out site-local
option 224 and then access this within iPXE as ${224}.
You can combine this with the "choose --default" option to give
something like:
choose --default ${224} selection && goto selection
If you don't want to use a dedicated DHCP option and server-side logic,
then you can do this within the iPXE scripting language using recursive
variable expansion. For example, to select a default based on the
default gateway address:
set default_192.168.0.1 winpe
set default_192.168.1.1 fedora7
set default ${default_${gateway}}
Hope that gives you some ideas.
Michael
