 Replying to [comment:4 David Kergyl]:
 > Thanks, Sascha.  This sounds like a serious problem, if there's no way
 to recover overlay space.  Perhaps the warning message should be "The
 overlay is almost full; backup your active Journal work to a new USB stick
 NOW, and get a new Sugar-on-a-Stick."
 AFAICT Sugar has no way of noticing that the overlay ran out of space.

 > The wiki should also be updated to warn new stick users about the
 importance of limiting downloads, including updates and activities, on 1Gb
 It already
 does], but I agree it's not clear enough. If you have some time, it would
 be nice if you could improve those warnings.

 > FWIW, when I erase Journal entries on a new stick, Sugar reports the
 Journal space as being larger (even though the overlay space must be
 smaller if you are correct).  Is journal space not the same as overlay
 No, that's the problem. The filesystem is sized at 2GB, but reduced by
 using various hacks to make it fit on a smaller USB stick. Sugar sees only
 the original size of 2GB.

 Bernie has
 [http://lists.sugarlabs.org/archive/soas/2010-January/000654.html manually
 installed] a SoaS image directly on a USB stick, without using the size
 reducing hacks, thereby eliminating the issue. Unfortunately none of the
 tools seem to support this installation method, though.
