Persistent Live-USB case study

1. Download usb from https://shared.com/at41j5zp74?s=l
2. extract image with p7zip 7z e dd-kingstion.7z
3. burn image on 1G usb stick to get physical entity

dd if=dd-kingston of=/dev/sdb

Here be dragons! check "of" device with dmesg so you don't damage your healthy disk drive

learn how Live-USB is build / configured

• /dev/sdb1 * 1 2445311 1222655+ 6 FAT16 is boot partition
• files and dirs on root are:

 casper/  initrd.img  ldlinux.sys  opt/  stts.sh  syslinux.cfg  vmlinuz

• contents of syslinux.cfg

DEFAULT vmlinuz APPEND boot=casper initrd=initrd.img rw vga=788 live_media=/dev/sda1 splash quiet-- TIMEOUT 1 PROMPT 1

• after boot, squashfs is mounted from casper dir, on root is mounted live_media from /dev/sda1 (that's why bold)
• bootable part of stick was created copying right files and syslinux.exe d:
• initrd.img we can explore [1]
• i believe stts.sh is userscript... in top of it is: mount -t vfat /dev/sda1 /live_media -o remount,rw,noatime
