...t and execute the init process. Is realroot the '/' or the empty directory created (in the cpio archive) ? How should I go about it? Using pivot_root, chroot ...? Am not very clear with these. 2. At the time init(from initrmafs) is called, is there any file system mounted? Thanks Rachita.

...t support threads. Am i right here? So when I 'exec' linuxrc after mounting initrd, it will never return to the calling function, and all that linuxrc does is to pivot_root to the real_root_dev. How do I execute the real init in this case? Please tell me if I am missing something. Thanks Rachita.

...g functions in the early user space and want to use initramfs for this. I understand this can be achieved using 'initrd' or by making changes in the 'usr/gen_init_cpio.c' file. Can someone kindly give me pointers as to how to go about this. I am looking at the 2.6.x kernel. Thanks Rachita.

...How would you do this if the initramfs is being loaded dynamically in the kernel (ie having the initramfs as initrd ) Because in this case, you will say root = /dev/initrd and specify 'initrd' as your 'initramfs source file' How will you specify the second initrd source? Thanks Rachita.

Hi In linuxrc(on initrd), there is one 'mkrootdev /dev/root' for creating root device, which it later mounts as root. Where does it get the information regarding the real root device from? Thanks Rachita.
