What are the Supported Options in fuse-overlayfs?

[ragnarov]

Does fuse-overlayfs support all options of mount -t overlayfs ?
It seems to recognize volatile but not recognize metacopy=on .

unknown argument ignored: metacopy=on

here is the command used :

fuse-overlayfs -o lowerdir="${v_lowerdir}",upperdir="${v_upperdir}",workdir="${v_workdir}",volatile,metacopy=on "${v_merged}"

I don't think metacopy is implemented, I think all of the supported options are listed here: https://github.com/containers/fuse-overlayfs/blob/main/main.c#L194
