Description of Problem: I cannot get a serial console to spawn in runlevel 1, only runlevels 234 and 5. Version-Release number of selected component (if applicable): How Reproducible: Every time Steps to Reproduce: 1. Add the ffollowing line to /etc/inittab: s0:12345:respawn:/sbin/agetty ttyS0 9600 vt100 2. re-read the inittab (eg: /sbin/init q) 3. look for agetty running (ps -uaxxww | grep agetty ) 4) Drop to run level 1 or reboot into runlevel 1; Look for agetty running (eg: ps -auxxww | grep agetty ) Actual Results: agetty does not start from runlevel 1 Expected Results: agetty should run in runlevels 1, 2, 3, 4, and 5. Additional Information:
try adding the following kernel parameters to your bootloader: "single console=ttyS0,115200n8"
i've also usually used mgetty and not agetty for serial consolses spawned by init ...
Only console should be active in runlevel 1. Console needs to be redirected if you want remote serial console.
