How do XF "cron entries" work in XF 2.0.2? I ask, because I run my XF inside an alpine-lamp container, which lacks obviously the standard crap background processes /that a full linux distro has, most notably crond. Does XF use real cron, or /etc/periodic, or is it a fake cron, i.e., the job is spawned when an unrelated client request come in?
