Take advantage of Warner's nice new real GEOM aliasing system and use it for aliased partition names that actually work. Our canonical EBR partition name is the weird, not-default-on-x86-prior-to- this-revision "da1p4+00001234." However, if compatibility mode (tunable kern.geom.part.ebr.compat_aliases) is enabled (1, default), we continue to provide the alias names like "da1p5" in addition to the weird canonical names. Naming partition providers was just one aspect of the COMPAT knob; in addition it limited mutability, in part because it did not preserve existing EBR header content aside from that of LBA 0. This change saves the EBR header for LBA 0, as well as for every EBR partition encountered. That way, when we write out the EBR partition table on modification, we can restore any bootloader or other metadata in both LBA0 (the first data-containing EBR may start after 0) as well as every logical EBR we read from the disk, and only update the geometry metadata and linked list pointers that describe the actual partitioning. (This change does not add support for the 'bootcode' verb to EBR.)

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
