Hi Pierre,

Go for it!  :-)

Seriously, I=E2=80=99ve discussed profiles and all with several newcomers, =
who
hadn=E2=80=99t 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 =E2=80=98--list-profiles=E2=80=99.  Hopefully t=
hat makes a
centralized ~/.guix-extra-profiles less necessary, but either way, it=E2=80=
=99s
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=E2=80=99s (still!) not on-line, but I=E2=80=99ll try to update=
 the
berlin.scm configuration (in maintenance.git) so that it=E2=80=99s publishe=
d, if
nobody beats me at it.

Thanks!

Ludo=E2=80=99.
