* Structure that must be initialized for a diskless nfs client.
|
| 45 |
|
|
* This structure is used by nfs_mountroot() to set up the root and swap
|
| 46 |
|
|
* vnodes plus do a partial ifconfig(8) and route(8) so that the critical net
|
| 47 |
|
|
* interface can communicate with the server.
|
| 48 |
|
|
* The primary bootstrap is expected to fill in the appropriate fields before
|
| 49 |
|
|
* starting the kernel. Whether or not the swap area is nfs mounted is determined
|
| 50 |
|
|
* by the value in swdevt[0]. (equal to NODEV --> swap over nfs)
|
| 51 |
|
|
* Currently only works for AF_INET protocols.
|
| 52 |
|
|
* NB: All fields are stored in net byte order to avoid hassles with
|
| 53 |
|
|
* client/server byte ordering differences.

* I have defined a new structure that can handle an NFS Version 3 file handle
|
| 58 |
|
|
* but the kernel still expects the old Version 2 one to be provided. The
|
| 59 |
|
|
* changes required in nfs_vfsops.c for using the new are documented there in
|
| 60 |
|
|
* comments. (I felt that breaking network booting code by changing this
|
| 61 |
|
|
* structure would not be prudent at this time, since almost all servers are
|
| 62 |
|
|
* still Version 2 anyhow.)
