bug#22695: Binary Installation bugs and suggestions

[myglc2 <myglc2@gmail.com>]

I attempted to perform 'Binary Installation' on Debian 8 following ...

last updated November 04, 2015


Bugs:

A) The 4 occurrences of '~root' should be replaced with '/root'

B) What does 'On hosts using the systemd init system, drop
   /root/.guix-profile/lib/systemd/system/guix-daemon.service in
   /etc/systemd/system.' mean.

   FWIW, I tried ...

cp /root/.guix-profile/lib/systemd/system/guix-daemon.service \
   /etc/systemd/system/guix-daemon.service

... which did not work.


Suggestions:

 1)'guix archive --authorize < /root/.guix-profile/share/guix/hydra.gnu.org.pub'

   ... produced ...

   'warning: failed to install locale: Invalid argument'

   It is not good that the first guix operation that root attempts
   throws a warning.  Apparently this is to be expected, as careful
   study of '2.6 Application Setup' might suggest.  As a minimum, we
   should advise root that the warning is expected.

2) 'And that’s it! For additional tips and tricks, see Application
   Setup.' should be changed to say something like, 'This completes
   root-level install of Guix, However each of your users will need to
   first set their Locales and, if they intend to use X Window system,
   X11 fonts, as described in '2.6 Application Setup' before Guix will
   be fully functional.

3) Is it possible for root to pre-configure locales and X11 fonts for
   users?

4) What do we mean by, 'The guix package must remain available in root’s
   profile, or it would become subject to garbage collection—in which
   case you would find yourself badly handicapped by the lack of the
   guix command.'

   What does root have to do to assure that 'The guix package remains
   available'?
   
5) We should tell root how to verify that the installation was
   successful.  If 'make guix-binary.system.tar.xz' is intended to do
   this, we need to explain where to run it and how to verify the
   result.
   
6) Should a root 'guix pull' be recommended?

7) Given the "invasive" nature of this install, an uninstall script, or,
   as a minimum, explicit instructions of how to remove Guix, really
   must be provided.

8) It seems unlikely that a typical sysadmin will be willing to install
   Guix following the instructions as they now stand. This might be
   addressed by providing a Guix package for popular distributions.
   
9) We leave the root user with no locales or X11 fonts.  Do we recommend
   this?
