bug#73052: emacs 30 ssh: couldn't find a proper `ls' command

[Jesse Millwood]

I'm having this problem as well but with emacs 29 on a foreign distro 
trying to tramp ssh connect to a GuixSD system. I have added the same 
paths to the "tramp-remote-path" but I get the same issue. I did notice 
that the docs for the "tramp-remote-path" mentions that it needs 
"getconf" first, otherwise it just uses /bin:/usr/bin :

Default Directories represent the list of directories given by
the command "getconf PATH".  It is recommended to use this
entry on head of this list, because these are the default
directories for POSIX compatible commands.  On remote hosts which
do not offer the getconf command, the value "/bin:/usr/bin" is
used instead.  This entry is represented in the list by the
special value tramp-default-remote-path.

The getconf utility doesn't seem to be available in Guix though.
