DHCP 4.3.1-P1 on OpenWRT

[Olipro]

Greetings to the list,

I've created a port of the latest DHCP suite for OpenWRT, all is working 
fine, but I do have a few potential optimisations (namely to filesize) that 
the whole thing could benefit from:

Firstly, I've currently modified it so that all DHCP components will 
dynamically link against the shared BIND export libraries - what I would 
like to know however is whether these shared export libs are actually 
suitable for the BIND+dig+client itself; if not then presumably one could 
modify the export libs makefiles so that *all* source files are compiled 
into the library - in instances where OpenWRT is being built with both BIND 
and DHCP, this would be a space-saver.

In any case, having shared BIND export libs cuts down on a fair old chunk 
of the various programs' filesize.

My next ambition was to convert libdhcp into a shared library too; and I 
got as far as making it compile as a shared library, but that's about as 
far as it goes unfortunately since it appears that there is quite a 
cluster---- of function interdependencies between the various DHCP 
components and the library; move one or two functions into libdhcp and you 
open up a whole load more interdependencies and it starts to look like 
you're going to end up building a library that holds all the code and 
daemons that are nothing more than a main(); (I jest)

My hope is that someone on this list who has an involved knowledge of the 
inner-workings could comment on the possibility of reworking libdhcp so 
that it can trivially be built as a shared lib - this would be a tremendous 
boon for its deployability on embedded systems as the main concern is file 
size over everything else.
