Hi, We're working on a way to install packages into a chroot without actually using the chroot system call. A consequence of doing so is that maintainer scripts are run outside the chroot and are supposed to still operate on the chroot whose location is communicated via the DPKG_ROOT environment variable. We have created a salsaci job which patches 13 source packages, including src:shadow and shows that a chroot-tarball created that way is bit-by-bit identical to a chroot-tarball created the normal way: https://salsa.debian.org/helmutg/dpkg-root-demo/-/jobs The necessary changes to src:shadow can be found in bug #989712 as well as in the patch at the end of this mail. Thanks! cheers, josch --- a/debian/login.postinst +++ b/debian/login.postinst @@ -4,23 +4,23 @@ if [ "$1" = "configure" ]; then # Install faillog during initial installs only - if [ "$2" = "" ] && [ ! -f /var/log/faillog ] ; then - touch /var/log/faillog - chown root:root /var/log/faillog - chmod 644 /var/log/faillog + if [ "$2" = "" ] && [ ! -f "$DPKG_ROOT/var/log/faillog" ] ; then + touch "$DPKG_ROOT/var/log/faillog" + chown 0:0 "$DPKG_ROOT/var/log/faillog" + chmod 644 "$DPKG_ROOT/var/log/faillog" fi # Create subuid/subgid if missing - if [ ! -e /etc/subuid ]; then - touch /etc/subuid - chown root:root /etc/subuid - chmod 644 /etc/subuid + if [ ! -e "$DPKG_ROOT/etc/subuid" ]; then + touch "$DPKG_ROOT/etc/subuid" + chown 0:0 "$DPKG_ROOT/etc/subuid" + chmod 644 "$DPKG_ROOT/etc/subuid" fi - if [ ! -e /etc/subgid ]; then - touch /etc/subgid - chown root:root /etc/subgid - chmod 644 /etc/subgid + if [ ! -e "$DPKG_ROOT/etc/subgid" ]; then + touch "$DPKG_ROOT/etc/subgid" + chown 0:0 "$DPKG_ROOT/etc/subgid" + chmod 644 "$DPKG_ROOT/etc/subgid" fi fi
