The version 2 support has been tested (client+server) against FreeBSD-2.0, IRIX 5.3 and FreeBSD-current (using a loopback mount). The version 2 support is stable AFAIK. The version 3 support has been tested with a loopback mount and minimally against an IRIX 5.3 server. It needs more testing and may have problems. I have patched amd to support the new variable length filehandles although it will still only use version 2 of the protocol. Before booting a kernel with these changes, nfs clients will need to at least build and install /usr/sbin/mount_nfs. Servers will need to build and install /usr/sbin/mountd. NFS diskless support is untested. Obtained from: Rick Macklem <rick@snowhite.cis.uoguelph.ca>

* 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.

|
|
* comments. (I felt that breaking network booting code by changing this
|
|
