"gshadow" file does not get synced automatically in Etch while edited manually with "vigr"

Hi,

I get the following messages after I edit "/etc/group" file with "vigr" manually and save it

You have modified /etc/group.
You may need to modify /etc/gshadow for consistency. Please use the command `vigr -s' to do so.

What should I do to get the "/etc/gshadow" file also updated automatically as I change "/etc/group" using "vigr" ?

Thankyou so much

Kind Regards

Siju
