I'm not too sure about the "reserved" bit, because you can absolutely pass TTY1 (the install disk uses it for the ncurses UI, for example). So I'd rather rephrase this as "You can auto-login your user to any TTY, though it's usually advisable to avoid @code{tty1}, as by default it is used to log warnings and errors." > +You could also start your graphical environment via your > +@code{~/.bash_profile}.

When Guix Home is merged and there is an appropriate @file{home.scm} to show here, that'll be fine (or even good, if it's one of the first practical examples of Guix Home in the cookbook), but the thing this currently advertises looks like a bit of a hack. I'm somewhat sure, that sway users will intuitively find the `exec dbus-run-session sway` hack on their own -- if not, it ought to be documented as a part of sway, not Guix. WDYT? Leo

Basically all terminals and DMs have one. Also "a newcomer" → "newcomers" may be more appropriate in that it doesn't single anyone out, though in my personal opinion "newcomer" has some "only grade schoolers play on easy modo" vibes attached to it, particularly within a manual/cookbook. Perhaps to soften this, you should open up stating "While the Guix manual explains how to login a user to *all* TTYs, some might prefer a situation, in which one user is logged in to one TTY with the other TTYs either configured to login different users or no one at all." > +login.

Finally, though this is very personal, I'd put the note of caution from before here at the end, because now the reader has a complete understanding of what it is, that they are achieving. Putting the warning in the front might scare them away into not trying – which would be a security win for sure – but it could also happen, that they just skip over the warning and copypasta the code. Having everything together at the bottom is therefore preferable in my personal opinion, though again, that's very personal and others might disagree here. > +Note that the above code will automatically login the user > @code{alice} > +into @code{tty3}. You can auto-login your user to any TTY, though > it's > +usually advisable to avoid @code{tty1}, as by default it is used to > log > +warnings and errors. The explanation that alice is logged into tty3 is probably apparent from the procedure call, so putting the explanation of avoiding TTY1 among the caveats above has priority over when to explain, that alice is logged in to tty3. Still, you might want to split this up, so that the former goes in front of the explanation on how to login multiple users and the latter to the caveats. Regards, Leo

Date: Wed, 07 Jul 2021 11:29:12 +0200
I've pushed your code with some slight cosmetic changes, which I'll list below to master. - I changed the title of the section to easier fit into a menu. - I changed the example to mimic the one given in the manual - I rephrased the bit about encrypted root. Note, that applying the patch was a bit of a pain, as your send-email setup appears to set the following: Content-Type: text/plain; charset=y Please use UTF-8 in the future ;P Also, I'll probably receive a mail in a few hours stating that < jbranso <at> gnucode.me> can not be reached. Does this mail really satisfy the conditions one would typically have for having it in AUTHORS?
