So now the question is, why can't the (k)ubuntu disk manager see UFS  
partitions correctly? Or perhaps more importantly, how can I get it to see  
other partition types properly...

Actually, while we are on the topic, way back in win3.11/dos5 times I  
encountered a program that could read and write pretty much any disk  
format available at that time... tape, mac, amiga, commodor, the lot,  
including a whole bunch of really obscure ones that I'd never heard of. I  
can understand that one might have trouble with NTFS, being a closed  
source format, but why is there even an issue with other open source  
formats???  surely there is a library for accessing each or multiple disk  
formats?  Given that software existed 15 years ago that essentially  
allowed acces to several dozen existing commercial formats, is there such  
a project (perhaps sourceforge?) that doeswhat seems like a  
straightforward and usefull task - preferably without the user ever  
knowing they are being tricky!
