Radarr: [Bug, Aphrodite] Renaming files on cloud mounts result in downloading and reuploading files

[Silent-Remux]

Describe the bug
Renaming files on cloud mounts result in downloading and re-uploading files.

To Reproduce

ExecStart=/usr/bin/mergerfs \
  -o category.create=ff,async_read=false,cache.files=partial \
  -o dropcacheonclose=true,use_ino,minfreespace=0 \
  -o xattr=nosys,statfs_ignore=ro,allow_other,umask=002,noatime,nonempty \
  /mnt/local=RW:/mnt/remote=NC:/mnt/remote2=NC:/mnt/movies=NC /mnt/unionfs
ExecStop=/bin/fusermount -u /mnt/unionfs

According to mergerfs wiki, NC will exclude those paths from create policies (you can't create but you can change / delete).

Sonarr does not have this issue, it renames without downloading and re-uploading so this is a Radarr specific problem.

Steps to reproduce the behavior:

1. Go to a movie
2. Click on 'Preview Rename'
3. Click on 'Organize'
4. Watch the file download via ncdu /mnt/local/Media and then reupload.

Expected behavior
File to be renamed by not downloading the file.

To provide further clarification, this is how I have my path mappings set.

EDIT: Radarr devs have confirmed this bug is a result of switching to dotnetcore.
