Sorry ... I dont have much control over it ... I just do the best I can.

Yup! 1.5.3

Right ... However, there seem to be device routines in device_linuc.c that
I need to circumvent. So, I created a device type of evms (dev->type ==
PED_EVMS_DEVICE) and added it to device_linux.c. For example, you dont ever
do seek operations in evms. All i/o is LSN based and relative to the start
of the storage object.

Ok, you mean to say ... malloc a PedDevice in evms and fill in geometry,
size and stuff?

Everybody else (including parted) seem happy with the partition scheme.
That is why I believe I have the PedDevice info wrong or am missing some
info.  I'll step through the code some more.


>YUCK!  Yes, I think this is crazy...

Could you elaborate?  The basic idea is to malloc a ped_device. Then, call
to get a new ped_disk which will cause libparted to probe the disk's
partitioning scheme, attaching a partition list to the ped_disk. Later,
ped_disk_xxx routines can be called to: add, delete, resize, commit
partitions.
