when restoring a 1.2.3 config to 2.0RC1 the PPPOE username and password are lost (they are in the XML file).

ALIX 2D3 LX800

on a 4GB CF Card:
pfSense-2.0-RC1-2g-i386-20110226-1633-nanobsd.img.gz

updated to:
2.0-RC1 (i386)
built on Wed Mar 23 10:22:32 EDT 2011

LAN (lan) -> vr0 -> 192.168.45.1
WAN (wan) -> pppoe0 -> 10.0.0.246 (PPPoE)
OPT1 (opt1) -> vr2 -> NONE

attached is the xml config file with identifiable data obscured - external IPs now 10.0.0.x

I also get the following. Hopefully nothing serious.
