All correct. But a system using systemd (and hence cgroups) will
put an application either into some default cgroup (which will
very probably not have the required privileges, and hence needs
code in the application to move to another cgroup), or it will
require some 'registry' of applications that require a specific
cgroup to run in. Both are a real PITA compared to what whe have



There are three of them, and Alleline.
