Details

Our current dhclient-script relies heavily on ifconfig and route. It also relies on ip for ipv6, thus mixing old and new tools.

It is based on a script that was written in 1999, by a guy who was a complete shell scripting and linux noob, and is apparently completely unmaintained.

Fedora has its own version of the script ([1]), but that uses tools we don't have - it is still a much better start than what upstream dhclient provides.

Both scripts have a /bin/bash shebang, which is also bad, because I wanted to use dhclient+dhclient-script in initramfs, where I don't have bash.

This script needs to be replaced by something that doesn't use deprecated tools and doesn't necessarily rely on bash.

seems like the ipcalc fedora's script is using an app part of its initscripts package, not the one Arch has in community.

Correct. I forgot what their ipcalc was used for, but it seemed unnecessary at the time. In general, Fedora's script tries to do way too much.

@brain0: maybe use something like this instead?
http://www.linuxfromscratch.org/patches/downloads/dhcp/dhcp-4.2.4-P2-client-script-1.patch
LFS also has another patch from fedora: http://www.linuxfromscratch.org/patches/downloads/dhcp/dhcp-4.2.4-P2-missing_ipv6-1.patch
The first patch applies on the upstream linux dhclient-script which is almost identical to the one Arch is using.
