I want to run a thing that may disrupt the system (or remote access to it) if something goes wrong (for example, misconfiguration).To reduce problems I want to have a grace period after the system already started, but before dangerous service started.Requirements:Delay is applied only on automatic starting of the initscript, not when I /etc/init.d/whatever start manually;The script is not started until its dependencies are ready (according to usual rules in initscript headers);Boot process should go on, without waiting for the full timeout.How to do it more or less cleanly?Related: https://superuser.com/questions/460112/how-do-i-run-a-script-5mn-after-startup
How to make some initscript start after delay at boot?
