I don't think either of those is a good idea. If you want to configure
cgd in the kernel it should probably work similar to configuring
1.) The kernel looks on all blocks devices for meta information that tell
it how to auto-configure cgd volumes.
2.) If the meta information for any of the cgd volumes has the
"I want to be the root file-system" flag set (the same what
"raidctl -A root ..." does for RAIDframe) it becomse the

Not if it is done properly. The will not even notice it in that case.

Well, that would be a bug of the implementation. Other operating system
are able to completely detach a boot ramdisks.
