If you have that kind of complication in permissions, then you colud use "acl". Then these rules can be easly invoked

Code:

chmod a= D # You can clear standard permissions if needed
setfacl -m   g:G1:rwx,g:G2:w,g:G3:w,u:u3:rx,u:u4:rx   D

You need to use filesystem which support acl, for example "ext" and mount it that it use it, for example

Code:

mount -o remount,acl /
