Type /sbin/mount, /sbin/fsck, /sbin/reboot and so on, and it does work. Never tried using an setenv PATH /bin:/sbin:usr/bin:/usr/sbin(etc) in single user mode, but I reckon it works. Also note that vi doesn't work by default as it needs to write to /tmp. So mount /tmp or re-mount / to RW permissions.
