i never told or mean to tell that kernel contains software. i know linux is a kernel, and puppy is a GNU/linux OS. all i want to confirm is just like what you said in your EDIT section above, that i can replace my current main puppy files (vmlinuz, initrd, and .sfs) with ones in future release. than...

i'm using slacko 5.4. whenever new future released, can i easily use the new kernel from the new release for my 5.4? eg. just by copying the vmlinuz, initrd, and .sfs from the new release?
thanks for replies.
