I just upgraded from 6.1 to 6.2 (amd64) and I'm noticing a differing behavior with dhclient.
I use the -L option to write out the offered and effective leases. With 6.1, when a lease was renewed, the -L lease file was overwritten with the new information. With 6.2, when a lease is renewed, it appears that the new information is appended to the file specified by the -L option. I had to implement a workaround in the scan of the lease file for the information I need, and I've got that working again. But the lease file seems be increasing in size with each lease renewal (or when a lease is obtained via a system reboot). I had an ISP that put a 5 minute length on their leases, and I have a concern that a short lease length like that could generate a large -L lease file due to the appends. Is this new behavior of appending to the file, rather than overwriting it, expected behavior? Thanks.
