Recently i have ported LDM support to the FreeBSD.
LDM uses 1Mbytes to store its database. All disks that are used by LDM have this database.
When the disk is partitioned with MBR, LDM is stored in the last 1Mbyte. When the disk
is partitioned with GPT, one partition is dedicated to this database.
LDM is not just partitioning scheme, it is also LVM and can do RAID0-5.
This is how Microsoft and Veritas have resolved this problem.
