I am aware of that. :) I thought about something like optionally
installing it from the DRBD-MC and starting the browser with it or
something like that.

Well you can log in as a user if you have permissions for the commands
that are required, but you probably know that... The SSH part of the code
and the commands used to operate on Pacemaker are logically separated from
the rest of the code, so it is quite easy to change this or offer a choice
to use something else, if such need arises.

I still trying to make the basic things to work, but I should get to this
pretty soon.
