Subject changed from [smart_proxy_dynflow_core] "PID file /var/run/foreman-proxy/smart_proxy_dynflow_core.pid not readable (yet?) after start" to [smart_proxy_dynflow_core] "PID file /var/run/foreman-proxy/smart_proxy_dynflow_core.pid not readable (yet?) after start"

Smart proxy dynflow core writes its pidfile into /var/run/foreman-proxy/smart_proxy_dynflow_core.pid. However /var/run/foreman-proxy is created by systemd-tmpfiles (and configuration provided by foreman-proxy). If /var/run is backed by a volatile storage which gets emptied on reboot and the machine reboots, smart proxy dynflow core may be started earlier than systemd-tmpfiles created the needed directory, leading to this issue.
