The following happens:
1. The partition type is swap, but it contains ext3
2. parted reports the partition as ext3 partition
3. you tell partman to use this partition as ext3 partition
4. partman does ped_partition_set_system(ext3) for it
5. however partman sees that the partition was ext3 previously and
concludes that the partition table is unchanged. Thats why partman
doesn't write it to the disk
The API of parted doesn't provide functions to access the partition type
and thats why partman has no way to find out whether your assignment of
the partition as ext3 requires changes in the partition table or not.
The solution (not nice) would be to write the partition tables
unconditionaly.
