           Summary: NetworkManager (or dhclient) always sets full hostname
                    instead of short one.
           Product: openSUSE 11.1
           Version: Factory
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Major
          Priority: P5 - None
         Component: Network
        AssignedTo: tambet@xxxxxxxxxx
        ReportedBy: seife@xxxxxxxxxx
         QAContact: qa@xxxxxxx
                CC: mt@xxxxxxxxxx
          Found By: Development


Note that I have configured my system to not change the hostname via dhcp.
Hostname is stoetzler.suse.de.

After boot without network or with netcontrol I get:

seife@stoetzler:~> hostname
stoetzler
seife@stoetzler:~> echo $HOSTNAME
stoetzler

If now NM puts the interface up, i get the following:
seife@stoetzler:~> hostname
stoetzler.suse.de

And, depending on when I log in and thus when the HOSTNAME variable is set in
the shell, I also get HOSTNAME=stoetzler.suse.de

This confuses applications that store the configuration depending on the
hostname and it can also prevent X applications from starting (because the
hostname changed).

I now use the following to fix the issue up:
seife@stoetzler:~> cat /etc/NetworkManager/dispatcher.d/aa_fix_hostname
#!/bin/sh
read hostname < /proc/sys/kernel/hostname
hostname ${hostname%%.*}

However, when the lease is renewed, the hostname is overwritten again.

I'm not sure if this is NM's or dhcp-client's fault.
