From bd0b2db23154f700fbb94aa3a0a0752a52b5ea7b Mon Sep 17 00:00:00 2001 From: Thierry Bultel Date: Mon, 15 Aug 2022 13:17:10 +0200 Subject: [PATCH] support/testing/tests/fs/test_cpio.py: new runtime test It includes a simple test for the full cpio image, and a test of the dracut image. To validate that the dracut image is a subset of the full image, 'pv' is added to the image, and the test verifies that pv is not part of the image. Note that the real rootfs is not mounted at the moment, so pv is never available in the running image. Systemd and other init systems are currently untested.
