No patch attached because it's quite large. I apologize for the

This patch removes anaconda's use of libdhcp,
Why?
How will your patch improve Anaconda?[1]
libdhcp replaced libpump around F-5 or so. It's been nothing but
What was wrong with libpump?
trouble since then as it just wraps the client daemons and provides a
sloppy control system around talking to them. And the dhcp clients
don't even get executed correctly via this library anyway. It's been a
real pain to keep working and it just needs to go.
So, the patch has us directly configuring interfaces using libnl (which
is used by NM), and running the actual client daemons for dhcp and
dhcpv6 when the user requests configuration that way. The same way it
run on the target system.
How is/will Network Manager be better?
It's what the final system uses by default now and it's what we [the
installer team/distribution] would like to ultimately use for network
interface configuration during installation. If it's good enough for
the final system, it should be good enough for the installer. So, it's
more about using the same code for the same tasks.
Well, nm has (or should have, it was a bit limited when I last fought
it) much more functionality than the installer's likely to need.
Does the result use less RAM?
Not necessarily. But maybe.
Bear in mind that one of the major critcisms of Anaconda is its
ever-expanding size. Folk were pretty unhappy with it arount RHL7 when
some folk were trying to create an alternative, for smaller systems.
Back then, I recall, one could install with 64 Mbytes of RAM.
More recently _I_ was pretty unhappy when it took over 12 hours to
upgrade, in 256 Mbytes, from FC3 to FC5.
I favour a simple dhcp client that does an adequate job over a complex,
over-featured alternative.
