Why enabling systemd in WSL does not guarantee daemon permanence, and how services should actually handle WSL's own lifecycle events.
systemctl reports start-limit-hit when systemd's crash-loop protection trips — clearing the rate limit is a distinct step after fixing the real cause.
Using systemd's resource-control unit directives to cap CPU, memory, and IO for a service, and confirming the kernel actually enforces them.
Turning on systemd support in a specific WSL2 distro, applying the required restart correctly, and verifying services actually manage correctly afterward.

WSL distros ran without systemd for years, breaking software expecting PID 1 init. Here is why that gap existed and how it was architecturally closed.
A complete, working example converting a nightly backup cron job into a properly supervised systemd timer, with logging and failure visibility cron never gave you.
Understand systemd unit loading, dependency and ordering graphs, service readiness, activation, credentials, sandboxing and forensic debugging.
