As I understand it these implementations don't share the same goals.

- Jacques wants to limit the space that a vserver can use in the main host.
- Herbert want's to give the vserver's root user the ability to manage
his vserver's quota.

I'm I right so far?

- Jacques' approach doesn't need modifications to the quota package.
- Herbert's approach needs modifications to the quota package in the
main-server, and not the vserver's quota packages.

I'm still correct, no? :)

Both ways have pros and cons, has you can guess and none is the perfect
solution (C)... I'm not using quota right now, so I don't care :)

People that need this should speak up and discuss on what's best and
stop flamming around ;)
