FreeBSD gpart vs NetBSD

FreeBSD gpart is the operating system’s utility for managing disk partitioning through the GEOM class. It can create, add, delete, modify, resize, inspect, and attribute partitions, using schemes including APM, BSD, BSD64, LDM, GPT, and MBR. Adding a partition can request alignment for its start offset and size. Bootcode can be written into partitioning metadata or a specified partition. Dump and restore support saving a partition table and cloning it to multiple providers. Changes may remain pending until commit or be reversed with undo. Recover addresses corrupt scheme metadata, but choosing the wrong provider can damage another GEOM class’s metadata. Show reports partition details and supports libxo machine-readable output. Gpart is included in FreeBSD, which is free and offers self-hosted installation media for multiple architectures.
