# Compile on an old version of Linux that has barely the minimal build
# requirements for CMake. This tests that curl is still usable on really
# outdated systems.
#
# Debian stretch is chosen as it closely matches some of the oldest major
# versions we support (especially cmake); see docs/INTERNALS.md and it
# is still supported (as of this writing).
# stretch has ELTS support from Freexian until 2027-06-30
# For ELTS info see https://www.freexian.com/lts/extended/docs/how-to-use-extended-lts/
# The Debian key expires 2025-05-20, after which package signature
# verification may need to be disabled.
# httrack is one of the smallest downloaders, needed to bootstrap ELTS,
# and doesn not conflict with the curl we are building.
