[debian-mysql] Bug#708380: mysql-server-5.5: Upgrade from squeeze to wheezy fails due deprecated replication config

[Rudy Godoy]

Package: mysql-server-5.5
Version: 5.5.30+dfsg-1.1
Severity: important
Tags: upstream

While upgrading from squeeze I've faced an issue with a Slave server
which had the following replication variables configured on my.cnf:

master-host=hostname
master-user=username
master-password=password
master-connect-retry=60

syslog gave the following error:
May 15 11:35:31 slave-host mysqld_safe[28143]: 130515 11:35:31 [ERROR] /usr/sbin/mysqld: unknown variable 'master-host=hostname'
May 15 11:35:31 slave-host mysqld_safe[28143]: 130515 11:35:31 [ERROR] Aborting

I've tried to find the reason why they are not valid anymore on MySQL's
release notes without any luck!

I think it should be a good idea to have the changes in place before doing 
the upgrade leaving the system unusable and with no access to .debian 
maintainer comments.

thanks,
Rudy
