I see that I was not clear enough in describing the situation.
1) The "customization" USB stick that I was plugging into the XO
did __NOT__ have any .img file (nor fs.zip file) on it -- meaning
that even when this stick was recognized by OFW, no reflashing of
the NAND was being requested. [The stick only contained .xo files
in directory 'bundles' - I was trying to install some activities.]
2) Between the time when the XO was able to boot an unsigned
build, and when it was no longer able to do so (due to develop.sig
having been somehow erased), __NO__ reflashing the NAND occurred.
[Flashing usually has some output to the screen - there was none.]
3) What started my muddle was that OFW did not *recognize* the
USB stick (until much later, once the system was rebuilt, when I
tried unplugging the external keyboard from the XO). OFW would not
boot the "customization" stick - it jingled and let me invoke the
'ok' prompt (where commands I entered told me there was no u: device).
4) When, to recover from the muddle, I *did* reflash the NAND
(with the four-button press) it was with a completely different
"secured upgrade" USB stick which contained an image of a signed build.
Bottom line: In this instance it was not a reflash of the NAND that
erased the develop.sig from the /security directory.
