Sending a SIGINT to init will invoke the alsctrldel entry of the /etc/inittab . A SIGPWR will (in absence of /etc/powerfail) call the powerfail entry. In a common setup, sending SIGINT will cause a reboot and SIGPWR will halt the client system. In my Gentoo environment, I'm currently using
ca:12345:ctrlaltdel:/sbin/shutdown -r now
But I'm still using the so-called baselayout-1. Some time ago Gentoo have shifted to baselayout-2, which use openRC. To my knowledge, it's init don't respect this signals, too. Because of that, I decide to wait until the lxc-attach functionality is stable.
