Well, I think you=E2=80=99re really asking for a new feature; we need more = than just talk to a remote daemon. Updating profiles like =E2=80=98guix package=E2=80=99 and =E2=80=98guix pul= l=E2=80=99 do involve two things: 1. building the profile=E2=80=94this is done by talking to the daemon; 2. modifying things in /var/guix/profiles & co. GUIX_DAEMON_SOCKET addresses #1 but not #2. For #2, we would need to do something like Jakub did in (guix scripts system reconfigure), where the effectul bits can be transparently evaluated either locally or remotely. But really, that=E2=80=99d be a brand new feature, so I=E2=80=99m marking i= t as a wishlist if you don=E2=80=99t mind. :-) Thanks, Ludo=E2=80=99.

The store is the same on all machines, since /gnu/store, /var/guix and /home are all shared via NFS. As far as I understand the manual `guix copy` would= be useful for store to store transfers on different machines only.

This is a limitation in =E2=80=98build-aux/build-self.scm=E2=80=99:
;; Use the port beneath the current store as the stdin of BUILD. This
;; way, we know 'open-pipe*' will not close it on 'exec'. If PORT is
;; not a file port (e.g., it's an SSH channel), then the subprocess's
;; stdin will actually be /dev/null.
(let* ((pipe (with-input-from-port port
(lambda ()
;; =E2=80=A6
(if (file-port? port) ;<- here
(number->string
(logior major minor))
"none"))))))
We could work around it by letting the =E2=80=98GUIX_DAEMON_SOCKET=E2=80=99=
environment
variable through, along these lines:

It=E2=80=99s a bit hacky though, and won=E2=80=99t work with old Guix revis=
ions anyway.
However, for your use case, you could perhaps simply pull on one machine
and use =E2=80=98guix copy=E2=80=99 to send Guix elsewhere? Or even explic=
itly run
=E2=80=98guix pull=E2=80=99 on each node?

Hi,

aemon that
can be reached via SSH. Thus GUIX_DAEMON_SOCKET=3Dssh://master.<domain> on =
the
compute nodes. Running `guix pull` on master works fine (the variable is not
set here), but it does not on a compute node. Instead it fails with this er=
ror:

Obviously the socket on that compute machine is not working, because it=E2=
