Well, after setting the display memory to 7 Mb. it almost works. The only problem is that I can't seem to find the Menu bar. Usually it would sit just above the Windows start bar (or at the top of the screen if the linux default is to show the Menu at the top). Any windows that are open however remain on the windows desktop. So I supposed that this might be a limitation of jwm. >> I found 'Menu/Utilities/Resize Personal File' very useful because I >> really wanted to try copying /sage into a writable area so I could >> install optional packages like fricas-aldor. > > Wow, I didn't even know about that! Did this work. > Unfortunately no because the vmdk disk has a maximum fixed size of only 2 Gb. It might be better and probably not take much more space in the compressed file if this disk were at least twice as large. Also you might consider using expandable disks like .vdi instead of .vmdk. But I am not sure of the pros and cons of this choice. Using a Windows file system shared folder does not work because it does not support linux symbolic links. :-( In the meantime I created a new .vdi disk as workspace and I am playing with that. After copying /sage over to this disk I tried './sage -upgrade but something here is still read-only it seems... # ./sage -upgrade Testing mirrors...

And of course none of this is the kind of thing for which this virtual machine was really intended. Like you said earlier perhaps there is a need for somewhat larger version of this sort of virtual machine that includes enough to actually do some development. But just how big is too big? Is it really worth the effort? Puppy seems pretty solid but kind of in a "world of it's own" when it comes to installing packages etc. I guess the main advantage of this puppy is it's extremely small size for a linux distribution.
