Following on from my question about OS images, does the XO check the
integrity of a firmware file before writing it? bootfw.zip files can
be checked against the CRC, but what about the .rom files?
Thanks

In normal (!debug) mode logs are *tiny*. We have the right tradeoff.
There may be cases that need tightnening the verbosity -- do post /
file bug
... and the write I/O is now buffered. Early in the 0.84 cycle it was
unbuffered, and this greatly hurt performance. Even with the buffered
I/O, occasional writes will stall, resulting in activity code stall.
Future redesign might be to pipe the stdout/stderr to the Sugar shell
and have it write

In normal operation, they logs are tiny. So generally yes, the
tradeoff is worth it: you can report a useful bug.

anything at all? If

Thanks for the quick responses!! I know there are new Fedora spins coming
soon which I suppose would be more complete since Fedora 12 is relativetely
old and ARM is getting quite a lot of attention.
I just wanted to try the Fedora ARM experience as it is right now and Sugar
if it was possible.

I am forwarding this to Steven Parish, he is working on Sugar on Arm.
I think that he is targeting F15 because Fedora is planning on
releasing an official ARM spin.
I am not sure if he is on this list.

Are OS images checked for integrity by the XO before they are written

The schools we deal with don't always have reliable Internet, so some
failsafe mechanism to prevent them from using damaged images would be
helpful. We can't expect them to learn md5sum to ch

In testing for http://dev.laptop.org/ticket/10667, how X renders text
changes after I run Record-87 on XO-1 os7 -- the font specification in
~/.sugar/default/terminalrc is no longer in effect.
I want to manually change how Record-87 caused X text to be rendered.
