Commit Message

Peter Kjellerstedt Aug. 23, 2024, 5:06 p.m. UTC
These tests verify that the correct files are left behind when systemd
is inherited and depending on whether the systemd and/or sysvinit distro
features are enabled.

PATCHv2:
* Change LICENSE to MIT for the test recipes.
* Add EXCLUDE_FROM_WORLD to the test recipes.
