Lee,

That is a good question, and, as you might guess, I dont have a "real" answer, for it...

I can conjecture on it though... Maybe the "persistant home" is like the "Windows Swap File", kind of thing

As the size of the storage grows, the file will actually grow with it, maybe to the "maximum" that you have set for it ( 500 MB ) ???

You get my drift? In the Windows World, the "swap file" they use can be a maximum of the whole hard drive free space, but doesnt "initially" get set to that, it has a minimum, and then "dynamically" grows and shrinks to the needs, as the needs change. This could be the same thing that is happening with the persistant home ( ? ) -=- I know this is all conjecture, but, it could be proven... Create some files in your persistant home that exceed your 40 MB size, can you still add more files to the /home ? Does the "file" increase in size with new additions of created files that exceed your 40 MB size ? My guess is, if I was going to guess on this, you set a "cap" on your /home, that being the 500 MB, and the /home area doesnt need to be that actual size, at this time, so it is saving your "space" when it needs it, possibly at a later time...

I hope I am not going "out on a limb" on this one, I dont have a clue on it really, but, I do think on my feet pretty well, ( sometimes [giggle] )

Hope this, in some way, has helped,
