Well I know it wont boot, I wanted to know what exactly would be the behavior..
I don't have a clue what he said, so I can't say if it's right.
You may already know but again, boot sequence is as below ..
So, my senior said it will stop at swapper since swapper starts before init process.. (we may see this on Solaris)
* Hardware initialization.
* sched - The real-time scheduler, sched runs as process 0 .
* swapper - It manages the physical memory by moving process from physical memory to swap space when more physical memory is needed.
* Page Daemon - is used to move pages in and out of physical memory and to update page tables.
* The last step in bootstrapping the kernel starts the /etc/init process.
I simulated this problem by moving /sbin/init to /sbin/init.old and reboot and yes it panicked ..
How to fix without rescue disk?? don’t need rescue disk, just powercycle it again ..
Press e at grub and add init=/sbin/init.old at the very last in kernel line and Esc then Press b to boot ..
see attachment for more details ..
