Re: kernel cmdline: root=/dev/sdb1,/dev/sda1 "fallback"?

These all unpleasant tasks could be avoided if it was possible to have a
"fallback" device. For example, consider this hypothetical command line:

root=/dev/sdb1,/dev/sda1

You should use initramfs to achieve that.

All right.
I see that initramfs is attached to the kernel itself.

So it leaves me only a question: will I fit all tools into 300 kB (considering I'll use uClibc and busybox)?
