Description:
Turn a chroot environment into a bootable image
debootstick is used to generate a bootable image from a Debian or Ubuntu chroot environment (such as one generated with debootstrap, docker export, etc.). This image should then be copied to a USB stick or disk and used to boot any amd64 machine (BIOS- or UEFI-based). The embedded system is ready to be started live (no installation procedure needed), and is fully upgradeable (kernel and bootloader included).
