Thanks for reply.

I replaced break=y with init=/bin/sh.
In that case case system just hangs with the following message.
"Freeing unused kernel memory : 400k freed".

Thanks!!

My grub.conf is as following.


title  Linux Init Break
kernel /vmlinuz root=/dev/sda6 ro rootwait break=y
initrd /initrd.gz

What I expect is by adding *break=y* to cmdline,
init will pause early in the boot process and launch an
interactive sh shell which can be used for troubleshooting purposes.

But kernel is disregarding break=y. And it loads up without
launching  sh shell.

Is it the right way to launch interactive shell ?


I would remove the break=y and replace it with init=/bin/sh

What version of CentOS are you running?


You didn't mention what version of CentOS you are running. I also realized
that this kernel line looks a bit non-standard. What is the purpose of the
rootwait parameter in this context? Have you tried without it but including
init=/bin/sh ?

You're welcome. Glad I could help.
