Czech sorting installation

Correct czech sorting (included "ch") in mySQL is set using
`--default-character-set=czech` directive on mysqld daemon
command line, e.g. in `/etc/rc.d/init.d/mysql` file. After restarting
was impossible connect to server. Problem is in changed code page -
old indexes were created with different code page. Solution:
recreate whole database:

1 export data, `mysqldump --all-databases --add-drop-table > /tmp/mydump.dmp`

2 import data, `mysql < /tmp/mydump.dmp`

Mysqld normally need mysql database when starting, otherwise
cannot start. To overcome use parameter `--skip-grant-tables`
or `mysql_install_db` utility. Here is necessary add parameter
`--default-character-set=czech` to create correct indexes.
