init script for mariadb galera cluster

      Description

      Having a look into the init script from mariadb-galera-server-5.5 I see some things that are not good. Some of them also fit to mariadb in general.

      • kill -9 (See Bug #870310)
      • killall mysqld (Do I really want to kill all running mysqld?)

      Things that are not good for Galera or are missing for a better Galera support.

      • Relying on a credentials file (/etc/mysql/debian.cnf). This is always bad, because it is inconsistent. Restarting/Status-Check a server will break, because the credentials in the file does not match the ones in the database. I wonder why not use any socket-auth.
      • Missing Bootstrap for Galera. PXC ships with a bootstrap option. May be worth to think about it.
      • The --wsrep-recover Option is ignored. This will most likely prevent a SST after a crash, as it can be used to get the last committed seqno
