AFAICT is the monolithic nature of partman the problem.
Partman does partitioning, mkfs and matching devices to mountpoints.
If partman would be split in those three parts,
then we can reuse the matching of devices to mountpoints
and do the "partitioning" and "mkfs" elsewhere, e.g. in the "BOOTROM"
of the embedded device.
Another advantage of that split would allow partitioning with other
tools (think "partition magic", "FAI partitioner" or other favorites )
Rigth now it hard to do that and surely hard to do in preseeding.
