Quota does not work under SuSE 8.2!
On a standard SuSE 8.2 installation the quota module is not loaded into the kernel which is why
quotaon -avug
gives back an error.
Load the quota module manually with
insmod quota_v1
and
insmod quota_v2
To have those modules loaded on every bootup of the system please insert
modprobe quota_v1
and
modprobe quota_v2
in /etc/init.d/boot.local.
