I was following Paul Moody's mini howto in http://linux-embedded.com/pmhowto.html.

If I remember well, when the kernel >uncompresses the initrd, it tries to execute a file named /linuxrc. If this program >(or script) copies a filesystem into /dev/ram, it should work. Yes, initrd.img.gz has linuxrc file and your procedure might be correct. Some people recommended to use "rdev". Thus, I searched a site, http://www.tldp.org/HOWTO/Bootdisk-HOWTO/x703.html and http://www.linuxhq.com/kernel/v2.4/doc/ramdisk.txt.html. It means I can not use Paul Moody's howto? If somebody has experience to build an embedded linux onto a flash memory, he/she will know this problem well.
