Hostname not respecting search domain

Hello,


I have a machine running Trusty. I would have expected the output of `hostname -f` to respond with the hostname of the machine, followed by the search domain as set in /etc/network/interfaces or /etc/resolv.conf. For instance, if my search domain was set to `ajlanghorn.com`, and my hostname was `test01`, `hostname -f` should respond with `test01.ajlanghorn.com`.


Assuming I've not got any of the above wrong, I have a weird issue with the `hostname` command. Regardless of which flag I pass it - be that `s`, `f` or no flag at all - I always get the same response from `hostname` back, which is to give `test01` as the response.


There is a search domain set in `/etc/network/interfaces` and I've given one to `/etc/resolv.conf` using resolvconf, specifying the correct network interface.


Has anyone seen this before?


Thanks,


Andrew
