[giuseppe]

• add new WebAssembly handler: spin.
• systemd: fallback to system bus if session bus is not available.
• configure the cpu rt and cpuset controllers before joining them to avoid running temporarily the workload on the wrong cpus.
• preconfigure the cpuset with required resources instead of using the parent's set. This prevents needless churn in the kernel as it tracks which CPUs have load balancing disabled.
• try attr//* before the attr/* files. Writes to the attr/* files may fail if apparmor is not the first "major" LSM in the list of loaded LSMs (e.g. lsm=apparmor,bpf vs lsm=bpf,apparmor).
