permission issue

[glc650]

Trying to use bg-sync with linuxserver/radarr but I'm unable to use the rsync path (/downloads) in radarr due to permission issues. I've tried correcting this with the UNISON_USER, UNISON_UID, etc variables (setting them the same as the radarr container variables) but every UNISON_GID I specify is always in use (including the default). And when using radarr without rsync I'm able to bind the volume and use it inside radarr so I know I have the right GID/UID.

`version: '2'
