| ret2libc | hi! does ubuntu still uses initramfs/initrd? i'm trying to look into them, but i cannot find anything interesting. initrd just contains a microcode and the initramfs included in the kernel source ./usr has just /dev/console and root. | 22:01 |
|---|---|---|
| TJ- | ret2libc: you're only seeing the prefix | 22:36 |
| ret2libc | TJ- what do you mean? do you have ref/links? | 22:37 |
| TJ- | ret2libc: the microcode is 'prefixed' onto the initrd.img file as a binary concatenation | 22:40 |
| ret2libc | TJ- ok but where's all the /bin, /dev, /init, etc. stuff? | 22:41 |
| apw | lsinitramfs shows the full content | 22:49 |
| ret2libc | apw: whoa... nice! thanks a lot! now the only thing i need to understand is what's the difference between that cmd and cpio :) | 22:50 |
| apw | re t | 22:50 |
| apw | ret | 22:50 |
| apw | ret2libc: there are multiple cpio archives back to back in an initramfs | 22:51 |
| ret2libc | apw: thank you, now i know where to look! | 22:55 |
| TJ- | ret2libc: sorry; been working on something else. I wrote a script that extracts it if you want it: http://iam.tj/projects/ubuntu/initramfs-extract | 23:24 |
