I see for precise-proposed, the patch is to add a 30 second lease for
pxe agents. This is resulting the lease during pxe being added to the
leases file with a 30 second expiration as expected, but the expiration
is not being honored.
We are seeing machines given the ip from the 30 second lease long after
it had expired.
It appears dhcpd is not respecting the 30 second lease and still giving
the wrong ip to nodes.
Example:
Below are the leases for a machine that came up with the wrong ip. The
lease for 172.21.66.24 is supposed to be for 30 seconds, but it appears
it was not being respected, since the node would come up with .24 after
rebooting long after the lease should be expired.
