In my space on Fedora people I have some 1.6.8 RPMs. If folks install these, that's totally fine, so I wanted people to be aware of what they were.
Nobody really needs to upgrade.
What this is are:
* A workaround for a yaboot bug in koan --replace-self on PPC so that the call to /sbin/ybin will get a proper return code -- it worked already but koan was returning a failure because ybin was. If you aren't running PPC and using koan --replace-self, you will not notice.
* A fix for a cobbler registration snippet so it can rhn_register correctly for RHEL 2.1 systems. This is end of life except for those who have "Mission Critical" support so I don't think there are too many of those out there.
(Both of these are things needed for Spacewalk/Satellite.)
Anyway, this update is probably safe for 99.99999% of you to ignore, but didn't want to confuse anyone by not mentioning it.
