[doc RFC] Tame the Guix profile blizzard?

[George Clemmer <myglc2@gmail.com>]

ISTM our doc is a veritable "Profile Blizzard."


The term occurs 173 times in guix.texi


The "user profile" is referred to in multiple ways:

 (guix) Application Setup: "your Guix profile"

 (guix) Features: 'own “profile”', "per-user profiles", "their profile"

 (guix) Invoking guix package: "user’s own profile", "user’s default
 profile", ‘$HOME/.guix-profile’

 (guix) Invoking guix environment: "package profile"


The "system profile" is referred to in multiple ways:

 (guix) Using the Configuration System: "Globally-installed packages"

 (guix) operating-system Reference: "global profile",
 ‘/run/current-system/profile’

 (guix) Networking Services: "system profile"


An unnamed type of "environment profile" is produced by 'guix
environment'

 (guix) Invoking guix environment" ‘GUIX_ENVIRONMENT’ variable


An unnamed type of "custom profile" is produced by the 'guix package' -p
option.


(guix) Top mentions only an entirely different use of the term:

 * Invoking guix size::          Profiling disk usage.


(guix) Concept Index contains only (guix) Invoking guix package
references.


ISTM we can improve this situation as follows:

1) agree on a canonical term to use for the 4 types of profiles

2) update the doc accordingly

3) add a top level discussion of profiles

WDYT? - George
