Comment 48 for bug 8980

Hello,

it also prevents duplicity (Backup Software) from running:

Last full backup date: Tue Nov 2 10:12:12 2010
Fatal Error: Backup source host has changed.
Current hostname: localhost6.localdomain6
Previous hostname: lain.office.noris.de

Aborting because you may have accidentally tried to backup two different data sets to the same remote location, or using the same archive directory. If this is not a mistake, use the --allow-source-mismatch switch to avoid seeing this message
Duplicity failed.

For me the problem occurs because it adds "lain" to ::1 as an alias (which is wrong). The line looks like this:

::1 lain localhost6.localdomain6 localhost6
