Thank You Lennart,

your tip was the solution for my problem.
Now all works as expected.
Only one question remains: I do not understand, why the "@" in the directory-name is necessary or what it does.


The other question about the dependency-cycle remains open, but I presume, this is a problem between Vmware and Debian.

The Distro is a plain Debian 8.5 running on vmware 6.0

The Cycle comes from the init.d-file of the vmware-tools.
### BEGIN INIT INFO
# Provides: vmware-tools
# Required-Start: $local_fs
# Required-Stop: $local_fs
# X-Start-Before: $network
# X-Stop-After: $network
# Default-Start: 2 3 5
# Default-Stop: 0 6
# Short-Description: VMware Tools service
# Description: Manages the services needed to run VMware Tools
### END INIT INFO
I do not understand, how systemd interprets this information and builds its dependencies, this requieres more reading in the doku by me.


Thank You for Your quick help.
