civodul pushed a commit to branch master
in repository guix.
commit 2986995b85e76f12741fcdda8dd0e1a636620dec
Author: Ludovic Courtès <address@hidden>
Date: Tue Jan 24 00:45:11 2017 +0100
services: Create /var/log/wtmp upon activation.
This fixes a bug whereby /var/log/wtmp would never be created, and thus
accounting information would be lost.
* gnu/services.scm (activation-script): Create /var/log/wtmp.
* gnu/tests/base.scm (run-basic-test)["wtmp entry"]: New test.
