! 77: * At open time, this does:
! 78: *
! 79: * find interface - netif_open()
! 80: * RARP for IP address - rarp_getipaddress()
! 81: * RPC/bootparams - callrpc(d, RPC_BOOTPARAMS, ...)
! 82: * RPC/mountd - nfs_mount(sock, ip, path)
! 83: *
! 84: * the root file handle from mountd is saved in a global
! 85: * for use by the NFS open code (NFS/lookup).
