My intention was to let the NFS client run the modified kernel with a raised group limit. Then, the process in question will be a member of more than 16 secondary groups which will enable it to access files readable for these groups, be it on NFS or not. Where is the NFS server involved? Enforcing access limits is the client's business, isn't it?
