- Hardware Database Files
- The hwdb files are read from the files located in the
- system hwdb directory /usr/lib/udev/hwdb.d,
- the volatile runtime directory /run/udev/hwdb.d
- and the local administration directory /etc/udev/hwdb.d.
- All hwdb files are collectively sorted and processed in lexical order,
- regardless of the directories in which they live. However, files with
- identical filenames replace each other. Files in /etc
- have the highest priority, files in /run take precedence
- over files with the same name in /usr/lib. This can be
- used to override a system-supplied hwdb file with a local file if needed;
- a symlink in /etc with the same name as a hwdb file in
- /usr/lib, pointing to /dev/null,
- disables the hwdb file entirely. hwdb files must have the extension
- .hwdb; other extensions are ignored.
-
- The hwdb file contains data records consisting of matches and
- associated key-value pairs. Every record in the hwdb starts with one or
- more match string, specifying a shell glob to compare the database
- lookup string against. Multiple match lines are specified in additional
- consecutive lines. Every match line is compared indivdually, they are
- combined by OR. Every match line must start at the first character of
- the line.
-
- The match lines are followed by one or more key-value pair lines, which
- are recognized by a leading space character. The key name and value are separated
- by =. An empty line signifies the end
- of a record. Lines beginning with # are ignored.
-
- The content of all hwdb files is read by
- udevadm8
- and compiled to a binary database located at /etc/udev/hwdb.bin.
- During runtime only the binary database is used.
