  actually, i can sort of understand that selection's value in
include/applets.h:

#ifdef CONFIG_INSTALL_NO_USR
# define _BB_DIR_USR_BIN _BB_DIR_BIN
# define _BB_DIR_USR_SBIN _BB_DIR_SBIN
#endif

all it's doing (apparently) is redefining the destination install
directories from /usr/bin and /usr/sbin to, respectively, /bin and
/sbin, and leaving /usr open.  i can *imagine* this would be useful if
you wanted to reserve /usr for an NFS mount or something.

it's just that the help screen for that option doesn't even give you a
*hint* as to what the selection means or why you might want to use it,
that's all.  from a newbie's perspective, adding a couple sentences
there probably wouldn't hurt.
