Today I am giving my presentation about systemd/journald for a not very 
enthusiastic public. I would like some last answers on a ‘few’ questions.

I understood that you could let systemd start-up the services sequential 
for debugging purposes. How is that done?

Is it possible to change the limits dynamically? When I change the 
service files and do a reload, are the new limits used, without a reboot 
being needed?

One of the problems mentioned is that services can be started only when 
they are used for the first time. As I understood it, you can make sure 
that a service is always loaded, so that there is no waiting time the 
first time it is called.

I understood you could deny a service network connection. How is this 
done? Until no I could not find it. Is it possible to limit the 
bandwidth a service is allowed to use?

When virtual machines are implementd as a service. You need to let the 
host define the limits per guest I suppose?

How do you let a block-device be read-only for a service?

Any last tips about what to share?
