If using ZFS, you *could* create a file system with quota for each user's home directory in the jail. I'm not saying it would be pretty.... With UFS, I think you would have to ensure that UID/GIDs do not overlap between jails, at least for the users you want to be affected by quotas. That could be as ugly as the thousands of ZFS file systems. -- Scott Lambert KC5MLE Unix SysAdmin lambert@lambertfam.org
