This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig30AE321BAD0215151CE039B2 Content-Type: text/plain; charset=KOI8-R Content-Transfer-Encoding: quoted-printable Hi, Since after r221788 many people report about lost of access to their MBR partitions, i prepared new patch: =09 http://people.freebsd.org/~ae/mbr_geometry.diff It removes from GEOM_PART_MBR constraints to alignment to track. Now it is possible to create MBR partitions with exactly specified start offset and size, and they will not be recalculated by kernel. Also the patch adds new option "-g" to the gpart(8) utility. This option can be specified for "add" and "resize" subcommands. gpart(8) uses information about provider's "geometry" and does partition alignment how it did before for MBR. With these changes we give to users the choice how align their partitions and also we still able to use some "broken" partition tables. --=20 WBR, Andrey V.
