I'm afraid that I
1] poorly worded the report
2] misunderstood

OK, let me retry.

I have Gentoo installation, guix 0.8 built using my ebuild and installed into system.

According to this part of documentation
http://www.gnu.org/software/guix/manual/guix.html#Invoking-guix-pull

I should be able to call `guix pull' and my guix will be updated.

It's not written there that it will be installed to
~/.config/guix/latest but guix prints it in the end.


So, when I call it:

tcech <at> venom ~ $ LC_ALL=C LANG=C /usr/bin/guix pull
starting download of `/tmp/guix-file.cSPiQM' from `http://git.savannah.gnu.org/cgit/guix.git/snapshot/guix-master.tar.gz'...

waiting for locks or build slots...
updated GNU Guix successfully deployed under `/home/tcech/.config/guix/latest'

and then ask for version:

tcech <at> venom ~ $ LC_ALL=C LANG=C /usr/bin/guix --version
guix (GNU Guix) 0.8
Copyright (C) 2014 the Guix authors
License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>

I can see that still old version is used.

The problem is

- documentation is missing some important part that I need to set up
  environment so new version will be used (adjusting PATH and
  GUIX_PACKAGE_PATH?)

or

- guix should check for installation in ~/.config/guix/latest by
  itself and does not


Please, ignore the part with `guix package -i guix' - it will just
cause installation of third instance of guix and this one will show
higher version as environment is set for installed packages
correctly. And this part confused me before.

I hope I made it more clear now.

Thanks,

S_W
