help setup quota

["Bambang Purnomosidi D. P." <bpdp@3wsi.net>]

I am using unstable, so the quota package is 3.02-3

In this case I want to set quota for group student which have home dir in    
/home/student/<studentname>

Here are my steps:

1. install quota package
2. edit /etc/fstab:

    /dev/sda4	/home	ext2	defaults,grpquota		0	2

3. Create /home/quota.group and make it 600
4. reboot
5. # edquota -g student
 
    I made: soft=10000
                hard=12500

    since I want to setup soft limit: 10MB and hard limit 12.5 MB
6. Reboot
7. When I want to setup grace time:
    # edquota -t 
    No filesystems with quota detected


Did I miss something?

TIA
