From: Martin Pitt Date: Wed, 18 Jan 2017 11:21:35 +0100 Subject: Add env variable for machine ID path During package build, in minimal chroots, or other systems which do not already have an /etc/machine-id we get six test failures. Introduce a $SYSTEMD_MACHINE_ID_PATH environment variable which can specify a location other than /etc/machine-id, so that the unit tests are independent from the environment. Also adjust test-fs-util to not assume that /etc/machine-id exists. Use /etc/passwd instead which is created by base-files.
