- You can switch from standalone to remote /usr in the following way:
-
- 1) Create /sbin/net.info with the following contents:
-
- <client-IP> <server-IP> 0 69 0 0 <netmask> 0 ent0 1
-
- All IPs must be numeric. The last number specifies bnc, change to 0
- for DIX. /sbin/rc.boot reads this file to configure the network
- interface. Here we have no gateway between client and server and use
- standard ethernet.
-
- 2) Edit /etc/filesystems: Comment out the complete /usr:-stanza and add
- a new one with your server-IP:
- */usr:
- * dev = /dev/hd2
- * vfs = jfs
- * log = /dev/hd8
- * mount = automatic
- * check = false
- * type = bootfs
- * vol = /usr
- * free = false
-
- /usr:
- dev = /usr
- vfs = nfs
- nodename = <server-IP>
- mount = automatic
- check = false
- type = boot
- options = ro,fg,hard,intr,retry=3
-
- 3) Execute the command:
-
- bosboot -a -d <bootdisk> -p /usr/lib/boot/netdisk.proto
-
- with <bootdisk> being your bootdisk.
-
- With this procedure we have successfully installed a 32H that runs both
- as /usr client and standalone (for demos). Note that you must export /usr
- with root access and read-only to the client.
-
- Note that I don't take any responsibility for crashes and 888's :-)
-
- Hope this helps...
