# start aptitude when running within d-i.

# This is similar to debian-installer-utils/start-shell, but modified for
# tasksel: for example, we cope with already being disconnected from
# debconf, handle templates differently, and can expect that the terminal
# plugin is available if we're connected to debconf.

# passthrough of environment variables as in-target can't be used
# re-entrantly; it would be nice to fix this at some point.
