Share_inst , client_inst , and clone_client are tools that install the
system software for diskless workstations.
Share_inst installs the portion of the IRIX operating system that
diskless workstations can share. This shared software is known as the
share tree. A share tree can contain only one IRIX release; a separate
share tree must be installed for each additional IRIX release that
clients require.
Client_inst installs the software that is used exclusively by an
individual diskless client. This software, known as the client tree,
contains the non-shareable portions of an IRIX release, such as
configuration files and other private files that pertain only to a
particular client.
Clone_client allows you to install multiple client trees at once. By
feeding it a hostfile, one can install many trees with no interaction.
Also, clone_root can be either a share tree or a client tree.
For each IRIX release, share_inst needs a parameter file,
/var/boot/share.dat, to supply the necessary configuration information.
Share.dat is a template file: /var/boot contains a working copy of
share.dat for each IRIX release that the diskless server supports. The
working copy of share.dat for a given share tree is assigned the name of
the IRIX release that the share tree contains.
Since share.dat is a shell script that is invoked from share_inst, it
should always be executable. When modifying the file, a good practice is
to change only the strings within the double quotes.
share.dat contains the following variables:
DISKLESS directory prefix for the share root, client root, and swap
root
SHARE directory name for share root
SERVER_NIS indicates whether NIS is used for name lookups during
installation. This option will not work with non-SGI NIS
masters. The bootparam information which gets set in the
SGI NIS master takes time to propagate back to the
diskless server.

The client.dat file performs that same function for client_inst as
share.dat performs for share_inst. Client.dat contains parameters that
configure a specific class or workstation architecture.
The client.dat file contains the following variables:
CLROOT directory name for client root
SWAP name of the directory where the swap file will be created.
The swap directory must be on the same server as client
root.
SWAPSIZE size of swap file. The default is set to 20 MB.
NISDOMAIN NIS domain of client if the client's domain is different
than the server's
CPUARCH type of CPU architecture on clients in this class. If the
supporting share tree is configured for this class of
clients exclusively, this variable may be set in
share.dat.
CPUBOARD type of cpu board on the clients in this class. If the
supporting share tree is configured for this class of
clients exclusively, this variable may be set in
share.dat.
GFXBOARD type of graphics board on the clients in this class. If
the supporting share tree is configured for this class of
clients exclusively, this variable may be set in
share.dat.
MACH type of machine tag assigned to this clients in this
class. If the supporting share tree is configured for
this class of clients exclusively, this variable may be
set in share.dat.
VIDEO type of video option on clients in this class. If the
supporting share tree is configured for this class of
clients exclusively, this variable may be set in
share.dat.
Both share_inst and client_inst are shell scripts that call inst(1M) to
perform the software installation. They also modify files, like
/etc/fstab and /etc/hosts, in the resulting trees, so the diskless
workstation can be brought up correctly. When share_inst creates the
share tree, it populates the tree with the shareable files. By
definition, files whose pathnames begin with /usr, /sbin, /lib, and
/stand are shareable. When client_inst creates the client tree, it makes
a swap file and modifies client boot parameters. It also exports
necessary directories to the appropriate host.

-r release
Using release release. The file release.dat should exist in the
/var/boot directory.
-c class Using class class. The file class.dat should exist in the
/var/boot directory.
-h host Indicates the client tree is created for workstation named
host. The host must be a valid hostname, i.e. it should have
already been assigned an IP address. This parameter does not
have any effect when creating the share tree.
-f hostfile
A file containing a list of valid hostnames
-clone clone-root
Indicates that the client tree is to be created by cloning an
existing client tree or share tree clone-root is the full
pathname of the source client/share tree.
-d To remove the diskless tree. The default is to install the
tree.
/var/boot/share_inst -r 6_5
will create a share tree for a specific release 6_5. The
/var/boot/6_5.dat file should exist before you run the command.
/var/boot/client_inst -r 6_5 -c RACER -h goldfinger
will create a client tree for class RACER and machine goldfinger. The
/var/boot/RACER.dat file should exist before you run the command.
Please see the Diskless System Administration Guide for more details.

complete install. The NFS release notes contain additional installation
information not included in the guide.
