What is the justification for such a broad sweep? libc bump CAN NOT be made an excuse for cascaded bumps. FreeBSD does not record LIBC dependency into shared libraries themselves, so as long as libc sybols used by the shared library did not change ABI between libc.so.6 and libc.so.7, old shared libraries will happily work with both. If there are are symbols that are missing or have changed in libc.so.7 that prevent it from being a perfect superset of libc.so.6, can we consider adding them back instead, with FBSD_1.0 version and making changed symbols FBSD_1.1 or some such? Sure, this will break older unversioned -current binaries as they will start resolving to FBSD_1.0 symbols, but your bump will obsolete them too, so -current users will need to recompile either way. =20 I always thought that original LIBC bump was a mistake. Please consider this an objection until this matter is discussed in more detail. --=20 Alexander Kabaev --Sig_zi6CY+FpD+45XROPApJ8nJs Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFGRGI6Q6z1jMm+XZYRAqcvAKDVrfll748pP0VzFzfMDSiOwWpw6gCg4KJD VJiZvax8o+ftJcMnQvCLmZw= =mt1B -----END PGP SIGNATURE----- --Sig_zi6CY+FpD+45XROPApJ8nJs--
