Now, we are ready to collect everything we've just build and
carry that bundle to our SEGA Dreamcast. So, we create
a single file that will contain the content of the directory $INITRD.
But firstly, we have to chown everything to root:root for avoiding
error messages during the boot process.
$ su # cd INITRD # chown -R 0.0 * # cd .. # dd if=/dev/zero of=initrd.img bs=1k count=4096 # mke2fs -F -v -m0 initrd.img # mkdir initrd.DIR # mount -o loop initrd.img initrd.DIR # (cd INITRD ; tar -cf - .) | (cd initrd.DIR ; tar -xvf -) # umount initrd.DIR # gzip -c -9 initrd.img > initrd.bin # exit
The command mke2fs -f -vm0 initrd.img forces the formatting process
even if we're using a file instead of a block device. The option
-m0 prohibits the creation of the reserved space
for the super user. Now, you've archived everything into one single file.
