Veritas 4.1 encapsulation problem on V445

I installed VxVM 4.1 dozens of times and never had an issue until today. I rebooted after encapsulating the disk and see this:

VxVM vxvm-reconfig ERROR V-5-2-337 The encapsulation of the Boot Disk failed.
VxVM vxvm-reconfig NOTICE V-5-2-393 The system will now be rebooted.

The problem is a bad line in the /usr/lib/vxvm/bin/vxroot. This bug caused the my system to boot without the following lines in /etc/system:

set vxio:vol_rootdev_is_volume=1

So I had to boot off the network, mount up the drive and add them to /etc/system. After that everything worked fine. I found the answers here. In the future you should be able to edit vxroot before you boot. You might want to make it part of your jumpstart finishing script.
