Let me draw your attention to these two noteworthy bug fixes since everyone is likely to have been hit by those two bugs:
commit c9323a4c69d48bc9af3825674e43a3febbb42091 Author: Ludovic Courtès <l...@gnu.org> Date: Fri Feb 6 17:52:07 2015 +0100 guix package: Make custom profiles actual indirect roots. Before that, any profile generation built when '-p' is used would effectively become a permanent GC root because the symlink in /var/guix/gcroots/auto would point directly to /gnu/store/...-profile. * guix/scripts/package.scm (maybe-register-gc-root): Rename to... (register-gc-root): ... this. Remove conditional, and replace call to 'canonicalize-path' with (string-append (getcwd) "/" ...). (guix-package): Call 'register-gc-root' only if PROFILE is different from %CURRENT-PROFILE. * tests/guix-package.sh: Add test case. commit 3df5acf332fd7b5c21c09961eaa5353c1bd08c60 Author: Ludovic Courtès <l...@gnu.org> Date: Fri Feb 6 17:39:10 2015 +0100 pull: Always install the ~/.config/guix/latest symlink. Before that, if two users on the same machine ran 'guix pull', the second one would have the "Guix already up to date" message and their ~/.config/guix/latest link would be left unchanged---effectively preventing them from updating. * guix/scripts/pull.scm (build-and-install): Install the 'latest' symlink regardless of whether TO-DO? is true or false.
