How do you propose a distro to deal with this? Keep it enabled for a certain time (with a deprecation warning?) and then just to close the doors on users who still need it? How long will you support it after deprecation? I understand that dm-multipath is more favourable, but unless there's a riskless way to convert mdadm multipath into dm-multipath on old systems, I don't think we have the option of deprecating it, unless deprecation lasts for several years. --=20 .''`. martin f. krafft Related projects: : :' : proud Debian developer http://debiansystem.info `. `'` http://people.debian.org/~madduck http://vcs-pkg.org `- Debian - when you have better things to do than fixing systems =20 "the perfect gun is an idealist without any ideal." -- mc 900 ft jesus --oyUTqETQ0mS9luUI Content-Type: application/pgp-signature; name="digital_signature_gpg.asc" Content-Description: Digital signature (see http://martin-krafft.net/gpg/) Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkmvzOAACgkQIgvIgzMMSnWbdgCfYDKm4NPAjlfy6bRGkz90cocD lloAoKEeOvdfXqE8xkTNENcI6XrpSqmu =kZ+A -----END PGP SIGNATURE----- --oyUTqETQ0mS9luUI--
