je vais le tester, je te dirais après ce que j'en ai compris
EDIT : erf, j'ai installé quota mais j'arrive pas non plus à l'utiliser ^^
implementation of the disk quota system
QUOTA is implemented using the BSD system call interface as the means of
communication with the user level. This is based on the Melbourne quota
system which uses both user and group quota files.
J'arrive pas à traduire ça non plus xD
