I agree with your decision to include quotas by default. When I put them into the system back in the mid-1980's we had two 1 MIP machines with 4Mb of memory that supported the entire Computer Science department at Berkeley. Machine cycles and memory were at a premium and *any* overhead had to be justified. So I made sure that quotas were as lean and light weight as I could. In this day-and-age of huge memories and blindingly fast CPUs including quotas seems like a good idea. Not a lot of folks use them, but those that do would like to have them available. And for those that want a tiny footprint (embedded), they can easily strip them out. Kirk McKusick
