# Build an image used for all building actions
#
# We use the oldest Debian-based image that can build Nosey Parker without trouble.
# This is done in an effort to link against an older glibc, so that the built
# binary (which is *not* statically linked, but does not dynamically link with
# non-standard runtime libraries) can be copied out of the container and run on
# more Linux machines than would otherwise be possible.
#
# See https://github.com/praetorian-inc/noseyparker/issues/58.
