It's better than that. If somebody compiles glibc to not run on older kernels at all (tested at runtime) then the code is dropped. E.g., the current Fedora glibc does not support 2.6.8 or earlier. So, don't let the compat code be a factor in the decision making. --=20 =E2=9E=A7 Ulrich Drepper =E2=9E=A7 Red Hat, Inc. =E2=9E=A7 444 Castro St = =E2=9E=A7 Mountain View, CA =E2=9D=96 --------------enig047926DEBCFEF4EC2586E7CB Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFF7EA92ijCOnn/RHQRAgsbAKCZcV0zDM8GF5OGOMLP5/XJl0eT5gCfbDah ro/6A/SqdLS1qSlMLWQ1Z44= =9J0B -----END PGP SIGNATURE----- --------------enig047926DEBCFEF4EC2586E7CB--
