How can i create initrd image for a new(experimental) kernel without actually installing it. (Existing tools to create initrd based on config and details from installed kernel.)
Say i compile a new kernel with experimental features turned on, i have this in another separate partition. I would like to boot into this kernel, for that will old initrd work ? if i want to create a new initrd.img for new kernel without actually installing kernel, how can i do it ?
BTW, can someone clarify about initramfs ? will it be useful for my scenario ?
