* gnu/packages/ssh.scm (mosh)[arguments]: Add substitution for mosh-server and
-client. Remove unneeded 'wrap phase.
---
For some reason setting $PATH in 'wrap phase doesn't work anymore, the perl
script doesn't find it's binaries, so I substitute them there.

Can you clarify the situation where it doesn't work? I'm using mosh as a
server on Guix System and it's working for me.

I’m also using it both as a client and a server and it’s working fine for 
me.

Both the client and the server are on foreign distros.

Interesting. On my guix system it currently does this:

~$ mosh localhost
bash: line 1: mosh-server: command not found
Connection to localhost closed.
/gnu/store/8xfhfr75svf6lw3fl4pnj47f31hz04lr-mosh-1.3.2/bin/.mosh-real: Did not find mosh server startup message. (Have you installed mosh on your server?)

It's the same for remote guix systems.

Well, atleast the patch would save spawning a subshell ;)

I wonder, did you install mosh via config.scm? Or with `guix install
mosh`?

True, I think there's no harm with your patch.

mosh is installed in the user profile via `guix install`.
perl is installed via config.scm.

Ah. I had to install mosh via config.scm, probably to work around this
issue.

The environment created when logging in over SSH to use a
non-interactive shell (such as for starting mosh) is not a complete
environment and doesn't really work for packages installed with Guix.

We arranged so that system-level packages would work correctly in this
enviroment, but it's not trivial to design a solution for user-level
packages:

Ah, right. I ran into that when mosh’ing into the remote machine.

This is actually a bash limitation (or even bug, I’d argue), because it 
doesn’t have an initialization file to set the environment for both 
interactive and non-interactive shells.

zsh has ~/.zshenv, which is always read and is where I source
/etc/profile.d/*.sh (including guix.sh). So the solution was simply to 
change the login shell from bash to zsh.

I can confirm that mosh(-server) works in a system profile.
This patch would only save us a bash exec, not sure if it's worth it.
