## initscripts rely on mysqladmin from a different package
We have the problem that "/etc/init.d/mysql stop" relies on mysqladmin which
is in another package (mysql-client) and a passwordless access that's maybe
only available if the user configured his /root/.my.cnf. Can this be a problem?
* normal mode: not because the user is required to have it. Else:
* purge/remove: not, same as normal mode
* upgrade: not, same as normal mode
* first install: not, it depends on mysql-client which at least is unpacked
                 so mysqladmin is there (to ping). It is not yet configured
		passwordles but if there's a server running then there's a
                /root/.my.cnf. Anyways, we simply kill anything that's mysqld.

## Passwordless access for the maintainer scripts
Another issue is that the scripts needs passwordless access. To ensure this
a debian-sys-maint user is configured which has process and shutdown privs.
The file with the randomly (that's important!) generated password must be
present as long as the databases remain installed because else a new install
would have no access. This file should be used like:
	mysqladmin --defaults-file=/etc/mysql/debian.cnf restart
to avoid providing the password in plaintext on a commandline where it would 
be visible to any user via the "ps" command.

## When to start the daemon?
We aim to give the admin full control on when MySQL is running.
Issues to be faced here:
OLD:
        1. Debconf asks whether MySQL should be started on boot so update-rc.d is
           only run if the answer has been yes. The admin is likely to forget
           this decision but update-rc.d checks for an existing line in
           /etc/runlevel.conf and leaves it intact.
        2. On initial install, if the answer is yes, the daemon has to be started.
        3. On upgrades it should only be started if it was already running, everything
           else is confusing. Especiall relying on an debconf decision made month ago
           is considered suboptimal. See bug #274264
        Implementation so far:
        prerm (called on upgrade before stopping the server): 
          check for a running server and set flag if necessary
        preinst (called on initial install and before unpacking when upgrading):
          check for the debconf variable and set flag if necessary
        postinst (called on initial install and after each upgrade after unpacking):
          call update-rc.d if debconf says yes
          call invoce-rc.d if the flag has been set
        Problems remaining:
          dpkg-reconfigure and setting mysql start on boot to yes did not start mysql
          (ok "start on boot" literally does not mean "start now" so that might have been ok)
NEW:
        1. --- no debconf anymore for the sake of simplicity. We have runlevel.conf,
           the admin should use it
        2. On initial install the server is started.
        3. On upgrades the server is started exactly if it was running before so the
           runlevel configuration is irrelevant. It will be preserved by the mean of
           update-rc.d's builtin check.
        Implementation:
        prerm (called on upgrade before stopping the server):
          check for a running server and set flag if necessary
        preinst (called on initial install and before unpacking when upgrading):
          check for $1 beeing (initial) "install" and set flag
        postinst (called on initial install and after each upgrade after unpacking):
          call update-rc.d
          call invoce-rc.d if the flag has been set
