That is an interesting point which I can answer tomorrow. All I know is
the nis
hosts are some very old sun servers. But even if it didn't then it should
just
drop though to dns and certainly not cause a crash in a user level app. It
wasn't an issue in previous versions.
You'd think, but it could be either a glibc issue or something in how the
NIS server responds. I use NIS, but not for host info and I'll be curious
to see what happens when I upgrade to F-10 in the near future.
Btw the apps which crashed were yum, pidgin, firefox and thunderbird.
I
can try
some more out but I think it is pretty generic.
It likely is.
