Subject: lib/configs: add test program for ul_configs_file_list()
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3d57b9059a94c9e0ab6529fad3d24778086ee8ab;p=thirdparty%2Futil-linux.git

lib/configs: add test program for ul_configs_file_list()

Add a test program with command line options to test the configuration
file list functionality. The test program allows specifying custom paths
for /etc, /run, and /usr directories, project name, config name, and suffix.

This enables testing the priority ordering and file discovery logic
of ul_configs_file_list() from the command line.
