I had mysql-server-5.1 installed, then upgraded to mysql-server-5.5 and now upgraded to percona server (package percona-server-server-5.5). So now I have 2 mysql-server packages removed, but not purged (in "rc" state). I tried to purge mysql-server-5.1 and during this, it stopped the percona server!
dpkg -L mysql-server-5.1 /etc /etc/mysql /etc/mysql/conf.d /etc/init.d /etc/logrotate.d /etc/logcheck /etc/logcheck/ignore.d.server /etc/logcheck/ignore.d.server/mysql-server-5_1 /etc/logcheck/ignore.d.paranoid /etc/logcheck/ignore.d.paranoid/mysql-server-5_1 /etc/logcheck/ignore.d.workstation /etc/logcheck/ignore.d.workstation/mysql-server-5_1
How can I get rid from mysql-server-* packages without affecting the running system?
