systemd notify

Question

I did not find any discussions or pull requests regarding Vector's systemd service type and wonder if the notify type would work better than using ExecStartPre and catch all start-up problems not just those anticipated by the validate run

I like SD_NOTIFY because it's relatively simple to set up

Catching failed service restarts is important in my daily work, most recently using Vector across a fleet of CDN proxy servers

I have implemented notify in Chproxy and would be happy to participate in any such Vector work also

Hi @larry-cdn77, I am not very familiar with this but it sounds like a desirable addition.

I guess we have to test on:

• systemd with Type=notify
• systemd with Type=simple
• Non-systemd environment (should warn, not crash)

Also, this crate looks small and widely used: https://docs.rs/sd-notify/latest/sd_notify/
