Good catch.  I agree we’ll need to factorize that eventually.

Cron jobs may set the LOGNAME environment variable but no USER,
e.g. under Debian 7 (wheezy).  In that case 'guix package' fails to
use $localstatedir/guix/profiles/per-user/$user.  From a quick grep I
couldn't find more places in Guix where USER is used, so here's a
patch that just does it straightforwardly in two places in
scripts/package.scm, but perhaps a more generic solution would be good
for the future.

Subject: [PATCH] Try LOGNAME in addition to USER.

Notoriously, cron jobs may set LOGNAME only and not USER.  See
e.g. crontab(5) under Debian 7 (wheezy).

* guix/scripts/package.scm (%profile-directory)
(guix-package): Also try LOGNAME if USER is unset.
