I've applied the changes in Tramp, will appear with next Tramp 220.127.116.11
in GNU ELPA (around end of September). In the Tramp manual, ther is the
4.16.1 Changing the default remote shell
Per default, TRAMP uses the command ‘/bin/sh’ for strting a shell on
the remote host. This can be changed by setting the connection
property ‘remote-shell’, see *Note Predefined connection
information::. Other properties might be adapted as well, like
‘remote-shell-login’ or ‘remote-shell-args’. If you want, for
example, use ‘/usr/bin/zsh’ on a remote host, you might apply
(list (regexp-quote "/ssh:user@host:")
This approach has also the advantage, that settings in
‘tramp-sh-extra-args’ will be applied. For zsh, the trouble with the
shell prompt due to set zle options will be avoided.
