Permit reboot/shutdown init commands to a group instead only root

[alonbl]

Hello,

Currently the control pipe of init is accessible only to root:

$ ls -la /run/openrc/init.ctl
prw-------    1 root     root             0 Jan  9 01:43 /run/openrc/init.ctl

I wonder if you accept a patch to add a group (based on rc.conf configuration), so that non-root process may interact with init to perform shutdown/reboot. It is safer and simpler than using sudo or providing CAP_KILL to perform this using a signal.

What do you think?

Thanks,
