Comment(by satellit):

 Bernie's USB:

 http://people.sugarlabs.org/bernie/soas-2-blueberry-direct-2GB.img.xz

 works great as a real file ext3 USB. the 2GB .img can be expanded to any
 size you want: I have expanded it to fill a 4GB and a 8GB USB with
 gparted. Just write it to a larger USB/SD with dd. An additional benefit
 is that it can be edited while plugged in to a PC running Fedora.

 see:http://people.sugarlabs.org/Tgillard/soas-2-blueberry-direct-cleared-
 3GB.txt

 Text of e-mail I sent Today:
 "Soas needs a way for a SoaS USB stick to check the free space it has and
 do deletions of oldest journal entries and overlay files (or warn that it
 is almost full before writing to journal) before filling the USB up so it
 cannot reboot and becomes unusable."

 I see that the XO-1 software does this for it's nand....
