When I switch from runlevel 3 to runlevel 1 on my CentOS 6 box the output of runlevel is
# runlevel 1 S
I'd expect the output to be
3 1. It's not a big deal but I'm keen to understand the logic behind the output. The man page for runlevel mentions that the Upstart init daemon works differently from SysVinit but as far as I'm aware runlevels 1 and S are always identical?
