Go for it!  :-)

Seriously, I’ve discussed profiles and all with several newcomers, who
hadn’t really discovered that facility initially, and the discussion
obviously talks about how to use them, when to use them, and so on.

So I think a section in the Cookbook would be very welcome!

Yes, I was going to suggest ‘--list-profiles’.  Hopefully that makes a
centralized ~/.guix-extra-profiles less necessary, but either way, it’s
good in the cookbook to have a discussion of the various ways you can do
things and the various tradeoffs that ensue.

Would you like to turn that into a section of the Cookbook?

Note that it’s (still!) not on-line, but I’ll try to update the
berlin.scm configuration (in maintenance.git) so that it’s published, if
nobody beats me at it.

Thanks!

Ludo’.
