init 9 also works
Last modified: 2014-03-16 22:59:20 EDT
/sbin/init may work only with "0123456Ss" but '9' also works and it's not
defined at /etc/inittab
# init 9
init supports 0-9 and the special letter runlevels, we just don't define 7/8/9.

but # init 9 "works" . And the system is left in a _catatonic_ state. Did you
try it ?
It's doing what is (more or less) expected - it's switching to a runlevel with
no processes to run, so it kills everything.
As mentioned in the man page:
Runlevels 7-9 are also valid, though not really documented. This is
because "traditional" Unix variants donât use them.
Since this requires root access to do, it's not really a big issue, AFAICT.
Package name is now sysvinit in latest Fedora.
