Sometimes it is necessary to stop a generator from running. Either because of a bug, or for testing, or some other reason. The only way to do that would be to rename or chmod the generator binary, which is inconvenient and does not survive upgrades. Allow masking and overriding generators similarly to units and other configuration files. For the systemd instance, masking would be more common, rather than overriding generators. For the user instances, it may also be useful for users to have generators in $XDG_CONFIG_HOME to augment or override system-wide generators. Directories are searched according to the usual scheme (/usr/lib, /usr/local/lib, /run, /etc), and files with the same name in higher priority directories override files with the same name in lower priority directories. Empty files and links to /dev/null mask a given name. https://bugs.freedesktop.org/show_bug.cgi?id=87230
