# we create /var/lib/dpkg/arch inside the chroot either if there is more
# than the native architecture in the chroot or if chrootless mode is
# used to create a chroot of a different architecture than the native
# architecture outside the chroot.
# In theory, /var/lib/dpkg/arch is only useful if there are foreign
# architectures configured or if the architecture of a chrootless chroot
# is different from the native architecture outside the chroot.
# We nevertheless always add /var/lib/dpkg/arch to make a chroot built the
# normal way bit-by-bit identical to a foreign arch chroot built in
# chrootless mode.
