Insecure world writable files from XFS 1.0.1 ISO installer

[Simon Matter <simon.matter@xxxxxxxxxxxxxxxx>]

When installing from the ISO RH7.1-SGI-XFS-1.0.1, all system config
files and directories which are not part of an RPM are installed world
writeable (mode 666/777). This was mentioned on this list before but I
didn't realize that it happens with the 1.0.1 installer ISO.
Is there an easy way to modify the installer to get around this problem
or is it better to use the 1.0 ISO and upgrade packages after the
install?

I'm just worried what to do with all those already installed system
because a
chmod -R go-w ... is not a good solution.
