<p>Update</p>
<p><br>
</p>
<p>Well a few more networking issues have been solved. thanks to
Davlet, and Moh at CENGN.</p>
<p><br>
</p>
<p>We have had a successful build of the 'compiler' and 'distro'
layers. The 'flock' layer built the rpms, but failed to update
the installer. It appears to relate to the loopback device. I'll
look into that tomorrow. <br>
</p>
<p><br>
</p>
<p>~350 RPMS failed to restore from upstream. None are critical to
any of our current builds. I don't plan to persu them any further<br>
</p>
<p><br>
</p>
<p>The mirroring job is throwing a lot more error messages than I'm
used to seeing. Many rpm download attempts are failing, and left
2000 new corrupt rpms in its wake. I am cleaning up the new mess
and adjusting the mirroring script to prevent download failures
from leaving us with corrupt repos. The download failures seem to
come in batches, so I'll reach out to CENGN to see if they had any
network issues that might explain the problem. <br>

<p>Aprox 7500 have yet to be assessed. Those remaining rpms

by builds might carry the same files name, but may contain
different content due to embedded file dates if not real
changes. Extra care is required to restore from the correct
source. If an exact match is unavailable, I may be forced to
use a source that is 'near' in time and therefore less
likely to contain anything other than trivial file timestamp
deltas. I'm still pondering the implications of such a
