Hi Claudius,

I see that you are using schroot. How is your progress on 'sudo' removal?

schroot itself, doesn't solve the 'sudo' problem, but it's very useful for 
running common tasks when setting up a chroot, like mounting filesystems, 
setting up binfmt etc.
So basically it extends the chroot command itself. 

I haven't heard of schroot before, but from what I gather it needs a

I've never heard about or noticed that schroot needs a  privileged service 
running in the background. Maybe I have to check this.
The main cause for introducing the schroot feature, was to have a already 
implemented framework, when setting up chroots (mostly related to setting 
up mounts).
Since a lot of chroot tasks running in parallel, if searched for a reliable 
chroot extension.

What are your experience with it? Could it be used for all parts that

That is what I think the docker container is for solving the 'sudo' problem.
Running schroot inside a docker container is now problems and behaves 
exactly the same, like running it without schroot.
