For the initial Essential:yes package set, mmdebstrap deletes the *.deb files itself after installing them. So you have to copy them out of the chroot before the deletion happens, so between downloading and extracting. Like so: $ sudo mmdebstrap --variant=apt --include='systemd-sysv udev' \ > --setup-hook='mkdir -p cache "$1"/var/cache/apt/archives' \ > --setup-hook='sync-in ./cache /var/cache/apt/archives' \ > --extract-hook="sync-out /var/cache/apt/archives ./cache" \ > --customize-hook='sync-out /var/cache/apt/archives ./cache' \ > unstable debian-unstable > > This will not work with all modes.

Maybe the ability of mmdebstrap to produce ext2 filesystems directly can be useful for you. You will then not need root privileges. Thanks! cheers, josch
