Subject: bug#61748: 27.2; Eglot should use shell-file-name when launching the language server for a remote file
Date: Mon, 27 Feb 2023 12:05:23 +0000

After a bit more investigation, I'm not sure this is a bug after all.
It might be.  My symptoms were the same as jeberger's but
my setup is slightly different (I'm not using zsh on the remote).

At least in my case, I was able to make Eglot/Tramp work successfully
by adding 'tramp-own-remote-path' to the 'tramp-remote-path' list.
If I do that, everything works as expected.

In my case I was using simply a /bin/sh on the remote server
and the user had a ~/bin directory that her ~/.profile adds to PATH.
But without the 'tramp-own-remote-path' fix, the shell used by Tramp
is not interactive and thus won't consider ~/.profile at all.

It's a bit unfortunate that in such a simple case, there is this hoop
to jump over.  But since at least it can be jumped over, I will add this
to the Eglot manual section on Tramp-related troubleshooting.
