I am glad to see this on front page of HN! Of course I use it mainly for additional web browser sandboxing, but it has some useful "side-features" that are really convenient - namely overlayfs/overlaytmpfs. This is great when I test new software and I don't want to clutter my home directory.

EDIT: Looks like it now fully supports X11 sandboxing.
