This is most straightforward and IMHO correct way to start whatever user wants. > It works OK, because the user (not greetd) launches Sway. > Should I care about your changes ? No, you should not care about stuff happening in script in `make-greetd-sway-greeter-command`. User session is started by scripts within `make-greetd-user-session-command` and `make-greetd-xdg-user-session-command`. Where user session command is specified by `command`, `command-args` and `extra-env` in ``. Most notable impact of this change, as noted in cover letter is that user session now factored out. Now you are able to pass instance of `` to any properly defined greeter, which are agreety, wlgreet and gtkgreet as of this change. I'm not RDE or guix home user, but I suppose that their entry point should be an instance of `` or combination of greeter and ``. > If I want to skip this bash step and make greetd launch sway > directly, > then I would need this script, otherwise, it is not necessary, > am I > right? Is there any upside / reason I should switch? Technically, you may set `command`, `command-args` and `extra-env` to sway, its required arguments and if necessary environment variables of `` instance, carefully considering `xdg-env?` and `xdg-session-type`. But, as I mentioned above, IMHO and from my experience, starting from .bashrc/.profile/whatever from user home and editable by user is more correct and straightforward.
