After upgrading from emacs-27.2 to emacs-28.1 on a Guix system, opening
files/directories via sudo using tramp no longer works.

Here's what's in the *Messages* buffer:

> Tramp: Opening connection nil for root@remq240 using sudo...done
> File error: Couldn't find a proper `ls' command [6 times]
> tramp-error: Couldn't find a proper `ls' command

Logging out after upgrade does not help.

Kind regards,
