Comment 6 Nick Bowler 2018-10-22 17:36:05 UTC

Looks like upstream came to their senses and re-added the NSS compat
module as part of the default set, after just one release without it.

  commit 64d1e08ea822bf47cb2796ad0f727136227f983c
  Author: Andreas Schwab <schwab@suse.de>
  Date:   Mon Oct 2 14:30:46 2017 +0200
  
      Move nss_compat from nis to nss subdir and install it unconditionally

      This has been tested that local lookup still works with and
      without an installed libnss_nis, and that NIS lookup works when
      libnss_nis is available.

So I guess the libnss-compat package is only required for glibc 2.26
exactly, and should block every other version.
