Subject: [PATCH] dracut.sh: add check for invalid configuration files
Emit a warning about possible misconfigured configuration files, where
the spaces around values are missing for +=""
Better report a possible source of problems. We can fix annoying false
positives later.
(cherry picked from commit dfe2247a43d6a216d9af533825c9a103e3b056cd)
Resolves: #1946245
