- Use two separate strategies: one to symlink from /etc to files in /usr/ and two to copy files from /usr to /etc. The latter is needed for some rare cases where symlinks don't work because the daemon runs in a chrooted environment. - Update tutorial and reference sections in developer documentation. Tests: - Unit tests works and are comprehensive. - Using the component in apps works. Signed-off-by: Sunil Mohan Adapa <sunil@medhas.org> Reviewed-by: James Valleroy <jvalleroy@mailbox.org>
