 * Structure that must be initialized for a diskless nfs client.
 * This structure is used by nfs_mountroot() to set up the root and swap
 * vnodes plus do a partial ifconfig(8) and route(8) so that the critical net
 * interface can communicate with the server.
 * For now it is statically initialized in swapvmunix.c, but someday a primary
 * bootstrap should fill it in.
