[systemd-devel] Transient hostname default behaviour

[Daniel Drake]

Hi,

I'm working on updating OLPC configuration for systemd-195 based on this info:
http://lists.fedoraproject.org/pipermail/test/2012-October/111230.html

I can't quite figure out the hostname thing.

We need to set unique hostnames for avahi; machines with the same name
cannot collaborate. Also, avahi does not like "localhost", it then
uses a different name which also conflicts with other systems in the
same situation. Generating/assigning our own hostnames has not been a
problem until now, but I can't get it working.


I tried writing the hostname "foo" to /etc/hostname and rebooting.
However, the "hostname" command still returns localhost. hostnamectl
shows:

Static hostname: foo
Transient hostname: localhost

avahi picks up the transient hostname, and runs into the problems
described above. :(

This part of the man page makes me think that the transient hostname
should default to the static hostname:
"the transient hostname which might be assigned temporarily due to
network configuration and might revert back to the static hostname if
network connectivity is lost"
but that seems not to be happening.

Any hints?

Thanks,
Daniel
