I have a requirement to extend that system to allow a mix of quotas per qtree, and short of exporting /etc off the root volume to an NFS client and programatically (or manually) editing it there then running an expect script to login to the filer and run "quota off; quota on" or "quota resize" I cannot see a way to achieve what I want.

If NFS-exporting /etc ist what you want to prevent, you could script it using SSH to remotely execute filer commands: - Parse /etc/quotas using rdfile and sed/awk/grep/whatever - Show list of qtrees and quotas, e.g. with dialog - Write changes back to /etc/quotas on the filer using wrfile - Call quota resize - Parse output of quota report to see if everything went allright

Btw, rdfile/wrfile need advanced mode iirc.
