Hi Jelle, thanks for your reply.

I am a grateful courtesy guest sharer of internet access in
a small office complex via cat5 to their switches, so it should
not be a WiFi problem.

I get DNS automatically along with ip from their server dhcp,
but I have other options I could explore.

I can't try the herd command right now, as I am in strictly "foreign"
mode at the moment.

--Ignorable note about that:
(I am busy making a ~/.my_login_ctl.d that will contain the means
to log in with and without guix profiles visible, and PATH etc set
alternately. The idea is so I can just use touch to select features
implemented as files to be sourced from ~/.my_login_ctl.d/my_login_ctl
which I'll call from ~/.bash_profile. (~/.bashrc is also modified),
and then log in and get guix and Shepherd/herd etc -- or not.

I'm hoping this will help me debug differences between plain ArchLinux
and the latter with guix binarily installed, with and w/o Shepherd/herd also.
as I don't expect my problems of /usr vs /gnu to go away for a while :-)

BTW, I don't want to define a whole different /home/me_for_alternate_mode,
I want to switch from console to console with Alt-Fx and start a new mode
at worst by touching a file or two and logging out and logging back in.)
--Ignorable note about that:--

If the ip number to guix.gnu.org is fixed and public, maybe I
could try putting it in /etc/hosts ?

If there is no objection, I'd like to try that.
TIA if posting the ip number, or explaining why not ;-)
