There's been a steady trickle of interest in Debian packages of version 4.1 of ISC's DHCP.
I've been a bit busy with Real Life of late, but I had made a start on the packages a little while ago. I got a good chunk of time today and have something close to what I'd be happy to upload to experimental.
There's been three main hold ups:
The upstream build system changed
Upstream switched to using GNU autoconf and automake and all of that jazz, so nothing behaved the way it used to. I used this opportunity to heavily refactor debian/rules and use debhelper more consistently and appropriately.
It was a new major version, so the "3" had to go from everything
For historical reasons dating back to before I was involved in the maintenance of the package, the v2 DHCP package was called "dhcp" and the v3 DHCP package was called "dhcp3". The resulting binary packages were called dhcp3-client and dhcp3-server and so on. It seemed incredibly lame continue calling the v4 packages with v3 names. While I was "de-threeing" everything, I decided that maintaining a monopoly on the name "DHCP" seemed a bit unreasonable, so I've renamed the source package to "isc-dhcp" and all of the binary packages now have "isc-" prepended to them.
I wanted to switch to Git for collaborative maintenance
This is the first package I've maintained in Git, on Alioth, so there's been a bit of a learning curve figuring out how to do everything.
What's still to be done
While the package currently builds, it's not handling upgrades from v3 versions, and I doubt I've expressed all of the dependencies correctly to even try such a thing. The kFreeBSD patches need redoing, as does the LDAP patches.
There's probably not much more to be done before I'd be prepared to upload to experimental, except do a bit of local testing to make sure everything vaguely works. I might get time next weekend to do that.
