bind-mount with different UID, GID

Is it possible to bind-mount a directory in another location so that all contained files and folders appear to have a different UID and GID?

Re: bind-mount with different UID, GID

bind mount is not a filesystem, it just another mount point that references some part of the same filesystem.

In any case, mount a filesystem with UID/GID is only possible on filesystems that does not support UID/GID perms. (for example FAT). If your filesystem is FAT you can mount more than one time, with differents UID/GID.
If the filesystem support UID/GID like EXT4, what you can do is... an overlay, then manually change each file and directory.

But all depends on what you want to do...

Why are you trying to do this? Maybe there is another solution to your problem...
