Thanks for the info Jarrod!

It's a race condition, we have tuned in 2.7 to 'win' more

serves to rectify it. The first pass failing is innocuous.
For info, the issue is the awk daemon we write seems to
occasionally take a surprisingly long time to start and bind the
socket. We probably could have also fixed it by writing a tiny C
daemon, but kept to scripting code since it's only a few seconds
paid for bmcsetup.

xCAT bmcsetup troubles
Hi all,
Putting together a rack of some Dell c6100 series nodes, and am
running into some strange bmcsetup errors.
Everything appears to be configured properly on the xcat
management node, both the compute and the BMC networks all ping
without an issue. When I tell a node to do a bmcsetup, it
displays the following error on the screen:
Unable to prove root on your IP approves of this request
It then waits for a random period of time, tries again and
always succeeds the second time with no errors being shown.
The management node does not have access to the internet, and as
a result it is also dumping these bind warnings out to
/var/log/messages. These only appear when the compute node is
requesting config parameters from the MN:

Mar 13 10:46:24 linux7mgt named[6915]: too many timeouts

Mar 13 10:46:24 linux7mgt named[6915]: too many timeouts
resolving 'L.ROOT-SERVERS.NET/AAAA' (in '.'?): disabling EDNS
Could these issues be a side effect of bind not having access to
the internet to do root DNS lookups? It seems unlikely, but
given that it seems to always succeed a second time, and after
succeeding everything works perfectly, I'm at a loss.
Thanks for any help!
