The file servers that maintain on-disk file systems like kfs, fossil, kenfs, etc. all do use groups in the expected way. Part of the reason they can easily do so is that they have the file that lists the groups. The in-kernel file servers and many of the user space file servers that don't provide persistent data storage do not fully handle groups. This isn't too surprising since they might well be running without a persistent disk-based file system present. So the fossil file system does use groups, but the server that provides /dev/sd00 does not. BLS
