i always wanted support for pxe.
is there a specific reason to choose nbd over nfs?

i'm confused, this whole thing is meant for clients, right?
what does the tftp/dhcp server has to do with the client?
also, do you think we could just merge this in archiso and always use
the nbd hook? (knowing that it won't do anything in 99% of the cases,
when people do a regular boot)
