Are you asking, in other words, what problems could come from fixing the bootcode automatically whenever it's needed?

I'm afraid I don't know enough to judge the former. [0]: Although I can't imagine a situation when that'd be the case, that doesn't mean such a sitaution doesn't exist. --=20 Chris Nehren --WplhKdTI2c8ulnbP Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (FreeBSD) iQJbBAABAgBFBQJTRMKcPhSAAAAAABUAIHBrYS1hZGRyZXNzQGdudXBnLm9yZ2Nu ZWhyZW4rZnJlZWJzZC1zdGFibGVAcG9ib3guY29tAAoJEB6OfWhX/6FTFvMP/jr6 dubyiXDHhvd3ZXoepZqP/9jsW2Rp8c9shl3P4hyES622hpptk2eDOAB+WGhMLWqo R3rkVvM3bBdvWgKFzd8joFExA4ghEJfJCvvG33AwRvP1u7iptwQj8M2wJ03aoKAz pZPp5WDQAb7q0qq0DwuSjaV5IdNcdSjTIqH2hZDOXdv7lBHjh/Me7bGJL4TcDVNi vDlNBfvZGDPJfCTfgtmsqH9IcnYYboBqnim5cocsG1GXoHXiYt3GnNBnFlNsVWT2 Xchz/VNWYqPz8BoDiCHmGTkpH7mAjzd1OgjChZD8p2CPiqN88NRY5t/zQZ0KhCGw Bk0tbcugjII9pst7GF8Y8i40xqxjF4pcH7ytB/reN98zKwwrJd1Mn1+kUvncnCfT r5eUCe82n98NddNqzUDHJW5ri2tQXhmIBUaEg2QIFJdyVQkggGeIgyStPDg4v7H1 ATDGgDyNbnigZwQc0IDjQFxLY+lEGKI9paxMTHzhdhtswwV/07skWzkb88fFuaM5 cmoEk81Yp2lDLM+gVaOZq9qLQYc0WJx8ZMOsdJe2zOy7o9W/cYh0+L7FqHiwHRRz MQqd9MIjS4+d1r3jArIt7ma/70PCj+GtEMdvAvhrrLh+fHM0tUwZx1/beY9IqMP2 2pfdRVVFYanskCbpXtpe/pQ0r+/rUzkdbHcAaqhm =WSvT -----END PGP SIGNATURE----- --WplhKdTI2c8ulnbP--
