When I made my own initramfs I was operating under the "RAM and disk space
are cheap" assumption and did it the easiest way possible:
I included the *entirety* of /etc, /bin, /lib{32,64} and /sbin
Then I wrote a small bash script for /init
Throw the kernel and initramfs on a USB stick, install GRUB on said USB
stick and call it a day. If anything breaks, well I've got all the command
like repair tools included so it's no big deal to fix as long as the bash
script sends me to a command line if it has any problems.
