this isn't particularly easy to fix, as the kernel post-install script would
have to figure out what you'd done to your grub.conf.  If Jeremy/Peter have any
ideas that could be a quick-fix for this, I'm all ears, but I don't think
there's a great deal we can do this in situation.
Comment 2 Robert Greimel 2005-05-10 06:31:09 EDT
Yes, you will need to change the post-install script. But I think that it should
be easy to fix. You will need to parse grub.conf. Look which entry is the
default and check if the default boot entry (seperate by title) contains kernel
or chainloader. If the default boot entry contains "kernel", make the new kernel
the default. If the default boot entry contains "chainloader" keep it as the
default. In this case, depending on where you add the new kernel entry, you
might have to update the number on the default line.

Fixed in anaconda to not set UPDATEDEFAULT=yes for the case where you're default
to another OS.
