Under the 2.6.0 kernel source tree , there is a folder named 'usr' , there are makefile and related files in it to make out a initramfs_data.cpio , when making kernel , this initramfs_data.cpio will be made out together , then it will be placed into kernel from __initramfs_start to __initramfs_end . and the data in this space will be write into /initrd.image .
As I know , at the end of init , a init file will be executed , it should either be /sbin/init or /etc/int , etc. I want to ask a NewBie question : is this init file located in /initrd.image or boot disk ? _______________________________________________ Kernelnewbies mailing list [email protected] http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
