+
+ fakechroot, fakeroot For --mode=fakechroot.
+
+ gpg                  To figure out the right signed-by value for distributions
+                      that apt doesn't know the right keyring for.
+
+ libdistro-info-perl  To figure out whether a distro is EOL or not and to
+                      figure out which security mirror to use because Debian
+                      bullseye and later use suite-security instead of
+                      suite/updates.
+
+ libdpkg-perl         To find out keyring paths.
+
+ mount                Needed in cases mknod is not permitted and device nodes

+
+ binfmt-support       Chroots for architectures that cannot be executed by the
+                      host CPU unless in chrootless mode.
+
+ ca-certificates      If using apt sources.list with https.
+
+ debootstrap          For using /usr/share/debootstrap/scripts/ to infer distro
+                      names from the symlinks and
+                      /usr/share/debootstrap/scripts/gutsy to figure out the
+                      default mirror URL.
+
+ distro-info-data     To get better data about new distros or EOL distros.
+
+ dpkg-dev             For the dpkg-architecture binary to turn a Debian

+Description: create a Debian chroot
+ Downloads, unpacks and installs Debian packages to either directly create a
+ directory which can be chrooted into, or a tarball of it. In contrast to
+ debootstrap it uses apt, supports more than one mirror, automatically uses
+ security and updates mirrors for Debian stable chroots, is 3-6 times faster,
+ produces smaller output by removing unnecessary cruft, is bit-by-bit
+ reproducible if $SOURCE_DATE_EPOCH is set, allows unprivileged operation using
+ Linux user namespaces or fakechroot and can setup foreign architecture
+ chroots using qemu-user.

+# FIXME: in an ideal world, debci would have enough computational resources

+#        build-essential and priority:standard that trigger it. But we are
+#        not there yet, so we must live with the situation that even if a
+#        package upload breaks the mmdebstrap autopkgtest, we will only notice
+#        either because another unrelated package triggers the autopkgtest
+#        or because this failed:
+#        https://jenkins.debian.net/job/mmdebstrap-jenkins-worker/
+## Using the hint-testsuite-triggers restriction we make all packages that are
+## put into the local archive by ./make_mirror.sh a trigger for the mmdebstrap
+## autopkgtest. This is essential, priority:required, priority:important,
+## priority:standard, build-essential, busybox, gpg, eatmydata, usr-is-merged
+## and usrmerge plus their dependency closure. The set is different depending
+## on the native architecture. Since we cannot depend on source packages and
+## to reduce the binary package set, only one binary package per source
+## package is listed here. If there are multiple choices, the binary packages
+## available on more architectures are preferred and then sorted by name.
+## Since library binary package names change frequently, this list has to be
+## updated regularly. Use the debian/compute_pkgset.py script to update the
+## list of dependencies.
