Subject: [PATCH] shared: add root argument to search_and_fopen
84b277
84b277
This adds the same root argument to search_and_fopen that
84b277
conf_files_list already has. Tools that use those two functions as a
84b277
pair can now be easily modified to load configuration files from an
84b277
alternate root filesystem tree.
