[debian-mysql] Bug#773282: mariadb-server-10.0: init script returns failure on success

[Frédéric Brière]

Package: mariadb-server-10.0
Version: 10.0.15-2
Severity: normal

Upgrading from 10.0.15-1 to -2:

  Setting up mariadb-server-10.0 (10.0.15-2) ...
  [ ok ] Stopping MariaDB database server: mysqld.
  [ ok ] Starting MariaDB database server: mysqld.
  invoke-rc.d: initscript mysql, action "start" failed.
  dpkg: error processing package mariadb-server-10.0 (--configure):
   subprocess installed post-installation script returned error exit status 1

Hmm.

  # service mysql restart; echo $?
  [ ok ] Stopping MariaDB database server: mysqld.
  [ ok ] Starting MariaDB database server: mysqld.
  1

The problem lies with line 122: /etc/mysql/debian-start no longer
outputs anything (at least for me), so the expression evaluates to 1,
hence the statement (because of &&), hence the script (because this is
the last statement).  Shell scripting is such a pain...

Using "if" (which returns 0) or appending "|| true" does the trick.
