How exactly so you pivot root? Simply chroot or something more involved?
chroot isn't enough, you need "real" pivot_root
chroot just changes the shells root point, pivot_root actually changes the root mount point and enables this trick to work
This is god-tier technique, kudos
Holy fuck
The man page has a good example.
