Configuration Format
Each configuration file is named in the style of
- <program>.conf.
- Files in /etc/ overwrite
- files with the same name in /usr/lib/.
- Files in /run overwrite files with
- the same name in /etc/ and
- /usr/lib/. Packages should install their
- configuration files in /usr/lib/, files
- in /etc/ are reserved for the local
- administration, which possibly decides to overwrite the
- configurations installed from packages. All files are sorted
- by filename in alphabetical order, regardless in which of the
- directories they reside, to ensure that a specific
- configuration file takes precedence over another file with
- an alphabetically later name.
