Some programs (e.g. xpra) create files based on the hostname and it'd be
useful to have control of this parameter.

There's another reason to have custom hostnames within the container as
well. From the guix manual[1]:

Right now my hostname is leaking to the container and that is certainly a
hint to my main persona.

Hi Vinícius,

AFAICS, ‘guix environment -C’ already starts contains in a separate UTS
namespace (see ‘%namespaces’ in (gnu build linux-containers)).

However, it does not attempt to change the host name, since you get a
non-zero UID inside that environment, you cannot change it.

What we could do is add a ‘--uid’ option to ‘guix environment’ and/or a
‘--host-name’ option.

WDYT?

Thanks,
Ludo’.

The --host-name option would work for me. That'd be enough to control
xpra unix socket names.
