This seems to be related to machines which change their hostname or IP
address after first boot; I'm not sure exactly which.  Everyone I
asked said that there's no way that the Xauthority file should care,
but it apparently does.  It's not a security feature; it was a feature
designed to minimize flash rewrites by putting .Xauthority in a tmpfs,
and this particular line (in /etc/rwtab) has been in the builds for a
*long* time now (since the 500 series at least; I believe it was added
by J5).

I'm not sure if we're seeing troubles with C2 machines because you're
doing "unusual" network operations on them, or if the problem is
actually in the xorg.conf (as Bernie suspects) or what.  As Bernie
said, we've got another approach the fixing the .Xauthority problem
for FRS (moving .Xauthority out of /home/olpc), but I can probably
remove /home/olpc/.Xauthority from /etc/rwtab for build -- er, 619 I
guess -- if that helps.
