Since this got no response, I wanted to add that fundamentally we just want
to get group quota limits. So right now we are reduced to calling lfs quota
-g group and then parsing the output of that call to something sensible and
printing to screen. Is this the expected protocol? Any thought on how to
make this work seamlessly through linux quota?
Thanks.
