Making Debian or Fedora persistent live images

- Live ISOs use read-only ISO9660 filesystem, making persistence tricky.
- Ubuntu persistence: kernel parameter "persistent", partition label "casper-rw", check via /cow.
- Debian persistence: kernel parameter "persistence", partition label "persistence" with persistence.conf.
- Fedora persistence: kernel parameters "selinux=0 rd.live.overlay=LABEL=foo:/bar", partition with "ovlwork" directory.
- Editing .iso for persistence often involves byte swapping in grub.cfg to avoid corruption.
- Fedora alternative: extract squashfs.img to ext4 partition, combine with FAT32 for persistent live USB.
