Installation de debian avec debootstrap

créer un lvm et un lv root et le monter dans /mnt/chroot, optionellement dans un volume luks. Si volume luks, penser a mettre /boot séparément

mount -t sysfs /sys /mnt/chroot/sys 
mount -t proc /proc /mnt/chroot/proc 
mount --bind /dev /mnt/chroot/dev 
mount -t devpts /dev/pts /mnt/chroot/dev/pts 
mount --bind /run /mnt/chroot/run

cryptsetup et lvm2
```
apt install cryptsetup lvm2 keyutils
```
Si on compte utiliser le mode mirror (raid) de lvm, il faut penser à installer mdadm sinon l'initramfs ne contient pas les modules nécessaires.
