Original GitHub issue: https://github.com/007revad/Synology_docker_cleanup/issues/13

https://github.com/007revad/Synology_docker_cleanup/blob/main/syno_docker_cleanup.sh#L69

readlink /var/packages/Docker/target/docker

returns an empty line.

readlink /var/packages/Docker/target

returns /volume4/@appstore/Docker

So I think this is a bug? Or at least Docker is behaving different in my NAS(?).

Can you tell me if there's a docker symlink in /var/packages/Docker/target

cd /var/packages/Docker/target
ls -al

Which version of DSM? Which Synology NAS model? Which version is the Docker package?

On my DS1812+ with DSM 6.2.4 and Docker 20.10.3-0554 the readlink /var/packages/Docker/target/docker command returns the location of the @docker folder.
