For clarity/record, crunchgen(1) itself does not generate the links.

You technically don't have to link to boot_crunch at all, for example:

/stand/boot_crunch ls

Another example:

/rescue/rescue vi

HINT: /rescue/rescue is also a crunchgen(1)-produced binary, just like /stand/boot_crunch in the mfsroot.
