Which command did you run exactly? Did you run it twice? The first time, it will ask you to edit a config file, and then prompt you to log out and back in again before continuing. After you do so, you'll need to run the same command again.I used the mk-sbuild wrapper, but as there was no discernible difference in disk space, and no folders magically appeared in /var/lib/schroot/chroots, I concluded that it had not worked.
The output of a successful run looks like this:
Code:
