Docker and libvirt images unmountable after upgrade

[primeval_god]

I attempted to upgrade to 6.8.3 from version 6.7.1. After upgrade Docker and VMs are not available. 

 

From my syslog I believe the relevant issue is here

Mar 9 20:39:24 Nexus root: sh: /usr/local/sbin/mount_image: Permission denied

First thing to do is to boot in safe mode to rule out any plugins, also if not needed delete the "extra" folder on the flash drive.

Ok so after much debugging i tracked down the issue to a user script that was running on startup. It was called replaceMountScript and it replaced the mount script with a custom one. The thing is i dont remember what exactly it was for.
