Version 1940 was commited by steve on 2011-05-10 10:18:44 +0100 (Tue, 10 May 2011) Set the partition size based on the actual size of the file. However it appears that arbitary sizes are not accepted, so we step through a list of sizes and take the first one that is large enough. The real restrictions are not known, so if anyone wants to experiment, please do.
