Selecting a specific runlevel at boot
OpenRC reads the kernel command-line used at boot time, and will start the runlevel specified by the softlevel parameter if provided, instead of default. For instance, you can choose whether to boot into the default, nonetwork or single-user runlevels with the following example grub.conf configuration:
/boot/grub/grub.conf
title=Regular start-up
kernel (hd0,0)/boot/vmlinuz-linux root=/dev/sda3
title=Start without networking
kernel (hd0,0)/boot/vmlinuz-linux root=/dev/sda3 softlevel=nonetwork
title=Single-user mode
kernel (hd0,0)/boot/vmlinuz-linux root=/dev/sda3 softlevel=single
