> Implement a disk resource isolator using XFS project quotas. Compared to the {{posix/disk}} isolator, this doesn't need to scan the filesystem periodically, and applications receive a {{EDQUOT}} error instead of being summarily killed.
> This initial implementation only isolates sandbox directory resources, since isolation doesn't have any visibility into the the lifecycle of volumes, which is needed to assign and track project IDs.
> The build dependencies for this are XFS header (from xfsprogs-devel) and libblkid. We need libblkid or the equivalent to map filesystem paths to block devices in order to apply quota.
