# startup the system
null::sysinit:/bin/mount -t proc proc /proc
null::sysinit:/bin/mount -t sysfs sysfs /sys
null::sysinit:/bin/mount -t usbfs none /proc/bus/usb
# set up a couple of getty's
::askfirst:/bin/sh
you can remove files in /usr/include and /usr/lib to save space.
when we design custom board, most drivers are under construction.
the initramfs need only ram, and a serial/jtag console driver is all that needed to start.
when you have tested your custom mmc driver, you may disable initramfs, and use
the mmc/sd as root device, with the kernel command line "root=/dev/mmc0".
you will need devfs to use mmc block device.

I made a filesytem project in that directory with all the options installed. There is nothing in sbin, only bin.. and they are all exe's. So in the directory ./target, I did "ln -s bin/init.exe ./init.exe" Any idea what I did wrong?
