In an emergency mode, basic vi knowledge, like basic stream editing, is pretty much required. Take any major distribution and many only ship busybox in various emergency modes. And busybox is pretty much only sed and vi.**
That's why most recovery tools look for VISUAL, and if it cannot be found, call 'vi' and, if that is not found, 'busybox vi'. Spend any time on GitHub on these various projects and you'll find lots of tickets/remediations addressing tools written by developers who expect nano or something else to be available, when it's not. - bjs **P.S. In a few cases that busybox is not built with vi (to save space), among other things, ViM or the full version is included in the emergency mode, possibly another editor or two -- hence why it is removed from busybox, as the full version exists. E.g., Fedora and RHEL emergency modes in more recent years.
