Hi Haidong, all As promised, I've fixed up a 5.2 branch to get rid of the old troublesome config files, and replaced them with the single baseline sample config - also any references in the build environment and in- tree documentation. See https://code.launchpad.net/~arjen-lentz/maria/5.2-zapoldsamplecnfs also proposed for merging. The baseline example I've used comes from the MariaDB DEB (Debian/ Ubuntu) packaging, and we can adjust it further. The new MariaDB packaging/build scripts should also be adjusted to use this file, replacing the old separate copy in the debian/ subdir.
