Hi,

Trying to use my emacs (on arch linux) with the guixsd system from the
0.13 image and ssh-daemon. By image, this is a fresh VM booted
guixsd-usb-install-0.13.0.x86_64-linux and about to install guixsd .

This Used to work with 0.12 image.

Now I have this set

  ;; ;; TRAMP and guix settings
  (setq tramp-default-method "scp")
  ;; https://lists.gnu.org/archive/html/help-guix/2016-10/msg00049.html
  (setq tramp-remote-path
        (append tramp-remote-path
                '("~/.guix-profile/bin" "~/.guix-profile/sbin"
                  "/run/current-system/profile/bin"
                  "/run/current-system/profile/sbin")))

And I try open path:
=/ssh:root@192.168.122.236:/mnt/etc/config.scm=

However this results in "pid died" message. (Sometimes my emacs even
crashes.)

Anyway, after a bit of debugging there is a tramp buffer that pops up
briefly and reports

env /bin/sh no such file

If in the VM, I do a hack like

ln -s /run/current-system/profile/bin/sh /bin/sh

Then tramp works without issue.

How can one configure tramp to work without the above hack?

(sorry this is more of an emacs then guix question)

The VM image should contain a valid /bin/sh already, doesn’t it?

With this ^^^ your additional paths are "shadowed" by the default
value of 'tramp-remote-path'.  Try to make it reverse:

   (setq tramp-remote-path
         (append '("~/.guix-profile/bin" "~/.guix-profile/sbin"
                   "/run/current-system/profile/bin"
                   "/run/current-system/profile/sbin")
                 tramp-remote-path))

However I don't think you need to set all these paths manually.

The different behavior between 0.12 and 0.13 may be caused by this
commit:

  http://git.savannah.gnu.org/cgit/guix.git/commit/?id=dc7010911dd3285fe9089352e92c77501595d100

i.e. your problem may occur because 'tramp-default-remote-path' is the
first element of 'tramp-remote-path' variable now.

> How can one configure tramp to work without the above hack?

I don't know if it will help you or not, but here is the setting I have
in my emacs config, which works for me for years:

(with-eval-after-load 'tramp-sh
  (push 'tramp-own-remote-path tramp-remote-path))

No it doesn't.

There is no '/bin/sh' on the guixsd-usb-install-0.13.0.x86_64-linux.xz
image/VM.

I'm just reconfirmed.

Perhaps there was on the 0.12 VM.

The above does make sense. I've tried it your suggested way and
unfortunately I'm getting the same results. For some reason my emacs
tramp is looking for /bin/sh still and has the same initial error
reported.

I think this wouldn't affect me as my emacs is from arch linux repositories?

The above didn't work for me either.

Oops, indeed.  I’ve just fixed it:
