# The removal of direct task installation support from live-build
# poses some problems. If the chroot has multiarch configured - for
# example, if we're building for amd64 - then dumpavail will show
# foreign-architecture packages which will have their own Task
# lines, but which we don't want to install. (Compare
# PackageContainerInterface::FromTask in apt, which restricts task
# expansion to the native architecture.) We therefore restrict our
# search to stanzas with Architecture: $ARCH or all.
#
# However, even this may not be accurate enough. At the moment I
# have no idea what happens if an Architecture: all package has
# different Task fields on different architectures. This is
# probably a lurking timebomb that we need to fix. In the meantime,
# the Architecture restriction at least saves us from abject
# failure.
