to store disk quota usage and limits, integrated with ffs metadata. Usage is checked by fsck_ffs (no more quotacheck) and is covered by the WAPBL journal. Enabled with kernel option QUOTA2 (added where QUOTA was enabled in kernel config files), turned on with tunefs(8) on a per-filesystem basis. mount_mfs(8) can also turn quotas on. See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html for details.
