# qemu-user) and that run-postinsts -> `dpkg --configure -a` must execute on first
# browser boot. Rootfs-time behaviour is asserted in the build log, not here; these
# cases assert what is observable on the target after that first boot.
#
# Numbered ahead of 80-dpkg.test deliberately: the runner globs tests/*.test in
# sorted order, and that suite's install/remove/purge lifecycle rewrites the same
# status DB no-unpacked reads.
