This is due to inittab having S for runlevel 1 as well.
Created attachment 209942 [details, diff] Avoid running single mode twice on shutdown
looks to me like that'll break `telinit S`, or am i missing something ?
You missed the new section in inittab installed with -r12 # new-style single-user su0:S:wait:/sbin/rc single su1:S:wait:/sbin/sulogin `telinit S` still works
sounds good to me then, thanks. added to 2.87-r1. http://sources.gentoo.org/sys-apps/sysvinit/files/inittab-2.86-r12?r1=1.2&r2=1.3
