### Traditional
This is what most users expect. A very early maintenance login prompt,
served by the bundled `/libexec/finit/sulogin` program, or the standard
`sulogin` from util-linux or BusyBox is searched for in the UNIX default
`$PATH`. If a successful login is made, or the user exits (Ctrl-D), the
rescue mode is ended and the system boots up normally.

that is not found in `$PATH`, the bundled `/libexec/finit/sulogin`
program is used instead. If a successful login is made, or if the user
exits (Ctrl-D), the rescue mode is ended and the system boots up
