When I made my own initramfs I was operating under the "RAM and disk space |
21 |
are cheap" assumption and did it the easiest way possible: |
22 |
|
23 |
I included the *entirety* of /etc, /bin, /lib{32,64} and /sbin |
24 |
|
25 |
Then I wrote a small bash script for /init |
26 |
|
27 |
Throw the kernel and initramfs on a USB stick, install GRUB on said USB |
28 |
stick and call it a day. If anything breaks, well I've got all the command |
29 |
like repair tools included so it's no big deal to fix as long as the bash |
30 |
script sends me to a command line if it has any problems. |
