[Koha-patches] [PATCH 25/28] Use /etc/mysql/koha-common.cnf instead of the Debian one.

[Lars Wirzenius]

koha-common.postinst now creates a symlink to the Debian one.
The sysadmin may replace that manually with something that allows
Koha to access a remote mysql server.

+Koha and MySQL
+==============
+
+koha-common's postinst script sets up the /etc/mysql/koha-common.cnf,
+and all scripts use that to access the MySQL database. By default, it
+is a symlink pointing at debian.cnf, and only works on localhost.
+If you wish, you can create a file /etc/mysql/koha-common.cnf instead
+of the symlink, and point it at a remote server. There is currently
+no tool to help you do that, but it should be fairly straightforward.
