From "man mount": grpquota / noquota / quota / usrquota These options are accepted but ignored. (However, quota utili‐ ties may react to such strings in /etc/fstab.) quota utilities indeed react to such strings in /etc/mtab too. Qutas aren't actually enabled when the mount options are used, they are enabled when the "quotaon" tool runs. I guess it uses some special syscall or ioctl to really turn quota on. Doing it at mount time instead, byt actually using those options, seems saner to me. But I guess they had their reasons. . .
