The %files list indicates which files on the build system are to be packaged. The list consists of one file per line. If a directory is specified, by default all files and subdirectories will be packaged.
%files /etc/foo.conf /sbin/foo /usr/bin/foocmd
The %files list can be made specific to a particular subpackage by adding the subpackage name, and optionally, the -n option:
%files bar
%files -n bar
The subpackage name and usage of the -n option must match those defined with the %package directive.
The %files list can also use the contents of a file as the list of files to be packaged. This is done by using the -f option, which is then followed by a filename:
%files -f files.list
