On FreeBSD, if tramp-own-remote-path is a member of, then using tramp's
sudo method raises an error similar to:
byte-code: `/bin/sh -l -c 'echo 9905dea968fdd4a549d307a722e8109b \"$PATH\"'' returns with error
On FreeBSD, /bin/sh does not accept the -l flag. bash, dash, and ksh
do, but that's not part of the POSIX shell requirements (see
http://pubs.opengroup.org/onlinepubs/009695399/utilities/sh.html), and
historically the Bourne shell doesn't.
This can be traced to tramp-get-remote-path, where it sends the command
"%s -l %s 'echo %s \\\"$PATH\\\"'", where the first %s is the shell.
I typically remove the -l flag in that function to make my Emacs work.
Again, this only applies if tramp-own-remote-path is a member of
tramp-remote-path; otherwise, that part of the code isn't invoked. It's
not there by default, but it's very useful.

Well, meanwhile Tramp doesn't raise an error anymore. It simply ignores
it, what's not a solution, I know.

Unfortunately, Posix does not specify how to force a login shell,
evaluating its ~/.profile and friends. If somebody knows a portable way,
how one could determine the $PATH settings of a login shell, I'll add it
to Tramp happily.
Best regards, Michael.

That's outside the scope of POSIX.

Traditionally, the bourne shell acts as a login shell if argv[0] starts
with '-', and that's how login(1) does it. Unfortunately, Emacs does
not provide a way to alter the value of argv[0] passed to the inferior.

This wouldn't help. Tramp needs to invoke a login shell on the remote host.
I have added a note to the Tramp manual about this restriction (the
remote shell must support -l in order to use tramp-own-remote-path). I
have no idea what could be done else, so I propose to close this bug.

Since commit 5126b7d6c201f95fde0d817a64620d152c1c15e1 in Emacs master,
Tramp supports the usage of the ENV environment variable. This could be
used as alternative in cases the remote shell does not support the "-l"
argument.
The Tramp manual says:
--8<---------------cut here---------------start------------->8---
Setting the ‘ENV’ environment variable instructs some shells to
read an initialization file. Per default, TRAMP has disabled this.
You could overwrite this behaviour by evaluating
(let ((process-environment tramp-remote-process-environment))
(setenv "ENV" "$HOME/.profile")
(setq tramp-remote-process-environment process-environment))
--8<---------------cut here---------------end--------------->8---
Could you please check whether this works for you, instead of using
`tramp-own-remote-path'?
Best regards, Michael.

No response, so I'm closing the bug. Feel free to reopen if it doesn't
work for you.
