Yes, I've found the same approach useful while developing an sd/mmc
card driver for the raspberry pi.  I started with this inital boot.rc:

#!/boot/rc -m /boot/rcmain

/boot/echo boot...
/boot/bind -c /boot /bin
bind '#p' /proc
bind '#d' /fd
bind -a '#P' /dev
bind -a '#t' /dev
bind -a '#S' /dev
echo -n rpi >/dev/hostowner
echo fdisk...
fdisk -p /dev/sdM0/data >/dev/sdM0/ctl
cat /dev/sdM0/ctl
dossrv -f/dev/sdM0/dos
mount -c /srv/dos /mnt
exec /boot/rc -m/boot/rcmain -i

And for sd driver testing there's no need for a paqfs - a handful
of useful programs can just be stuck into /boot directly:

bootdir
	boot.rc			boot
	/arm/bin/rc
	/rc/lib/rcmain
	/arm/bin/mount
	/arm/bin/unmount
	/arm/bin/bind
	/arm/bin/echo
	/arm/bin/cat
	/arm/bin/cmp
	/arm/bin/ls
	/arm/bin/ps
	/arm/bin/dd
	/arm/bin/xd
	/arm/bin/rm
	/arm/bin/mkdir
	/arm/bin/disk/fdisk
	/arm/bin/dossrv

But all this is now obsolete [see next message].
