Hi all,

I was going through the book "Hacking Ubuntu" by Neil Krawetz, in this
book it is said that never do kill -9 -1 as root.

in my office i tried this command as root on an RHEL4 machine

but there was'nt any system crash as i expected only the x-server got
crashed, and the commands like ps, ls were n't giving any o/p.

when i rebooted the machine everything was back to normal

my question why init process wasn't killed ?
