The After=syslog.target ordering is unnecessary these days. You should
be able to safely drop this.
Note that this will set up the cgroup structure only during late boot,
which should be fine for most cases. However, in some cases it might
make sense to initialize this due to early boot (for example, to handle
early-boot service, like udev). if you care for those add lines like
Starting the cgroup structure during early boot has the advantage that
you can make use of it during early boot already, but otherwise is not
necessary. It's up to you when you want to start this service...

Otherwise looks good!
