1. don't lookup the .host device during startup - startup happens before the boot.driver is loaded
2. lookup the .host device when a path-based or volumegs call is made.
3. when building a vcr, store the ptr so it can be dereferenced later, if needed.
1. deref vcr after fcr is created, in case it moved.
2. fcr and vcr go hand-in-hand, so no need to check each in the action table
3. add boot loader (not quite working yet)
