Owing to the present package choices, how many who do not wish to be
myth developers but that have a slave backends also used as frontends
pointlessly run never-used mysql server daemons? Consider typical
habits: A person gets 'mythtv' installed on system 1. Time passes,
they are happy. So, they decide to add a system. They repeat what
worked before -- they go to 'synaptic' and click 'mythtv' on system 2.
There are no words anywere there speaking about differences for a slave
backend. Not a different package, not commentary in the synaptic
environment about slave backends. So, 'mythtv' it is!! After all, who
would want to install a system that is 'not complete' as it explains
there? So, they run mythtv-setup 'just like last time' and put in the
details for the master backend. Viola. Done. Another useless mysqld
is born!
No real harm done, just wasted memory, a swap space, a small performance
hit.
