Hi,

Uwe pointed me to this list (mainly because of this particular thread) - so, 
to introduce myself, I'm 1/2 of yast2-network team and thought it could be 
really useful to subscribe, to be able to answer some questions, esp. those 
network related. But back to this 127.0.0.2 thing:

The purpose of 127.0.0.2 entry is that if the active network connection is not 
available at the moment,  a bunch of (buggy) applications (OpenOffice, bash, 
Firefox,...) try to do a hostname lookup, which of course can't succeed and 
takes long time to time out. Not surprisingly, users then complain that apps 
take up to 10 seconds to start if their laptop is currently offline.

But on the other hand, the entry being there breaks other things - active 
directory integration, printing, some proxy autoconfiguration scripts and 
some enterprise customers want it off by default.

There is a sysconfig variable controlling whether 127.0.0.2 entry is going to 
be included in /etc/hosts - WRITE_HOSTNAME_TO_HOSTS 
in /etc/sysconfig/network/dhcp and it is set to 'yes' by default. It can be 
overriden with product's control file - SLES11's one sets it to 'no'. 
Unfortunately, this is done in one installation client which is not called 
during autoinstallation, thus the value from sysconfig is used even though it 
should not be. 

To conclude - yes, this is a bug and it's been already reproduced in-house. 
Please file a bugzilla ticket. 

B.
