# We use `__nss_disable_nscd` which is `GLIBC_PRIVATE`, which means the debian
# tools don't know how to pick a minimum version of libc6 for it. It instead
# picks a version range like `libc6 (>> 2.31), libc6 (<< 2.32)` if built on a
# system with 2.31.
#
# The effect of this that we don't like is that we can't install the .deb on an
# OS with a newer libc than the build machine, because that version bound is
# strict.
#
# This rule somewhat rudely edits them out of substvars after they're generated.
# We're taking a chance here that glibc isn't going to delete or change
# `__nss_disable_nscd` soon in the future.
#
# See https://github.com/twosigma/nsncd/pull/61#issuecomment-1529166183 for the
# original discovery of this.
