qjackctl will create three files $HOME/.jackdrc (which contains the
command line that it will start jackd with based on the setup),
$HOME/.qt/qjackctlrc (which contains the UI configuration) and
$HOME/.qt/.qjackctlrc.lock which is locked in order to serialize access
to the qjackctlrc file if it is to be changed, these last two are
standard for all applications using the Qt application framework.
