The so called 'single' softlevel is a Gentoo fix for user specified runlevels with their own selected services. I don't have a pre-OpenRC box to check that it linked to, but I seem to remember that it went to runlevel 3 and adjusted services from there. The standard Linux runlevel called also single (confusing isn't it) stops before runlevel 3 and asks for a root passwd (or Control+D to continue). It can be called by appending 1 or S to the boot line. If you don't want to have to login with a password then I think you need to append 'init=/bin/bash' and mount as rw what fs you need to work on. You'll have to sync and umount before you reboot to be safe. Could also work with 'init=/bin/bb' for busybox - but I'm not sure. HTH. -- Regards, Mick
