fair enough, but something tells me that that man page (and,
consequently, the one shipped with nash) is incomplete.

i'm assuming that any command in the initramfs nash "init" script has
to come from one of two places, no?

1) built-in nash command, or
2) actual executable in the cpio initramfs directory structure (under
/bin)

so "mount" is a built-in nash command, as is "setquiet," as is "echo,"
as "mkdir," as is ... hang on ... what's with "hotplug"?  it's not
listed in the man page, and it's not a separate executable.  so what's
the story with "hotplug"?  and "mkblkdevs" for that matter?  if
they're nash built-ins, they're certainly not mentioned in the man
page.

or am i missing something?
