| |
The code in block/partitions/msdos.c recognizes FreeBSD, OpenBSD and NetBSD partitions and does a reasonable job picking out OpenBSD and NetBSD UFS subpartitions.
But for FreeBSD the subpartitions are always "bad".
Kernel: <bsd:bad subpartition - ignored
Though all 3 of these BSD systems use UFS as a file system, only FreeBSD uses relative start addresses in the subpartition declarations.
The following patch fixes this for FreeBSD partitions and leaves the code for OpenBSD and NetBSD intact:
