Sync 800 computer's "/"

am not sure why there is no support for file ownership beyond no one wanting it enough to do it but Synching is made to be cross compatible and managing ownership adds to the difficulties in maintaining that.

There is several issues:

• Windows and Linux/Unix differ here, so it would be difficult to impossible to syncronize file ownership between those operating systems.
• File ownership is maintained by the filesystem using a user und groupid. When you want to synchronize these IDs, you have to ensure that these IDs exist on each device and are consistent.
• You introduce severe security/privacy issues when you have inconsistent user/group IDs among your devices. Imagine what happens when you assign the wrong user to your files (e. g. Bob is ID 1000 on device A, Alice is ID 1000 in device B, Bob is ID 1000 on device C).
• This is IMO out of scope anyway. Syncthing is designed to run as a specific user who syncs his own files.
