- * 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.
- * The primary bootstrap is expected to fill in the appropriate fields before
- * starting the kernel. Whether or not the swap area is nfs mounted is
- * determined by the value in swdevt[0]. (equal to NODEV --> swap over nfs)
- * Currently only works for AF_INET protocols.
- * NB: All fields are stored in net byte order to avoid hassles with
- * client/server byte ordering differences.

- /*
- * I have defined a new structure that can handle an NFS Version 3 file handle
- * but the kernel still expects the old Version 2 one to be provided. The
- * changes required in nfs_vfsops.c for using the new are documented there in
- * comments. (I felt that breaking network booting code by changing this
- * structure would not be prudent at this time, since almost all servers are
- * still Version 2 anyhow.)
