[pkg-dhcp-devel] Bug#627825: isc-dhcp-client: Please provide a possibility keep the hostname untouched

[Axel Beckert]

Package: isc-dhcp-client
Version: 4.1.1-P1-17
Severity: wishlist

Since the inclusion of the patches in http://bugs.debian.org/609408,
dhclient always resets the hostname:

>     - fix setting of hostname in dhclient-script

I can't remember for how long this didn't work as it was expected to
(probably since the move of /bin/sh from bash to dash), but I find the
"fixed" behaviour very annoying, especially if a hostname is already set
via /etc/hostname or I explicitly configured in /etc/dhcp/dhclient.conf
to send a hostname.

I also don't understand why the hostname is currently always reset to
"anonhost-0263" on this machine as this isn't the hostname in the PTR
record of the IP I got via DHCP. It's also no existing other hostname in
the DNS domain I am currently in. I first suspected avahi-autoipd, but
deinstalling it didn't change this behaviour.

I currently use an exit-hook which resets the hostname to the one I
configured in /etc/hostname, but this is quite ugly as the hostname then
is changed twice on every lease renewal.
