I've done three more installations:

1. Set partitionsize to: 2000 MB
-> displays during installation: 1.9 GB
after the installation
-> df -m  /dev/hda1    -> 1788 (1M-blocks)
-> df -h  /dev/hda1    -> 1.8 G
-> df -H /dev/hda1    -> 1.9 G

2. Set partitionsize to: 2048 MB
-> displays during installation: 2.0 GB
after the installation
-> df -m  /dev/hda1    -> 1831 (1M-blocks)
-> df -h  /dev/hda1    -> 1.8 G
-> df -H /dev/hda1    -> 2.0 G

3. Set partitionsize to: 2.0 GB
-> displays during installation: 1.9 GB
after the installation
-> df -m  /dev/hda1    -> 1788 (1M-blocks)
-> df -h  /dev/hda1    -> 1.8 G
-> df -H /dev/hda1    -> 1.9 G

So it looks like the partitioner uses the 2GB = 2000000000 B system
(like the harddisk vendors do), instead of 2 GB = 2147483648 B.
Shouldn't the partitioner during the installation use the "correct"
system so that 2.0 GB in the partitioner creates a real
(approximately) 2048 MegaByte parition?

Kind regards
