what i need: i have a directory "/home/administration" with files belonging to group say "bosses". I've added say "john" and "bill" to group bosses. Now bosses can read and write in /home/administration. Now i want mark, anne and tom to be able to read data from /home/administration but not write. Others should not be able to do access it at all. So i created group "administration-read" and added mark,anne and tom to it. Now i wanted using nullfs or unionfs to clone /home/administration to say /nullfs/administration-read so it will be read only (no problem) but gid of files would be changed to administration-read. Tried multiple things, to no avail. Seems i don't really understand manuals ;) Any help how to do it this way or other way (but no ACLs please)?
