Q.  How can I run a command at boot / startup ?

A.  As root, put the commands you want to run in:

/etc/rc.d/rc.local
eg:
#!/bin/sh echo system started | mail root
And make it executable:
chmod a+x rc.local
This is the way it worked before systemd and it continues to work this way with systemd (There's an rc-local.service but you don't need to mess with it).
