cl_init - init program for diskless software installation
cl_init is the init(1M) program in diskless share tree. When client
workstation installs its software using the PROM menu, the workstation
uses the share tree as the root and process 1 runs cl_init instead of the
cl_init prompts the user with the following questions:
Do you want to use server XXX for software installation (y/n) ?
XXX is the default server name used in the tapedevice or bootfile PROM
variables. When doing installation, this default is the name of the
server that contains the share tree. If the client tree will be
installed on a different server, user should answer n here.
Enter server name :
Enter the correct server name for client tree. cl_init checks the server
name with the /etc/hosts file in the share tree. If the server name is
not in this host file, cl_init re-prompts the user for appropriate
Do you want to install client YYY on server XXX (y/n) ?
XXX is the server name, and YYY is the hostname that is set in the PROM
variable hostname or translated from netaddr using bootparamd(1M)
Enter password for autoinst :
If the autoinst login entry at server machine requires a password, the
user should type in the password at this prompt. Once the password is
accepted, the inst(1M) menu appears on the screen.
Ready to exit (y/n) ?
cl_init repeats the installation procedure again if the answer is n.
Otherwise, it sets the PROM variables netaddr and bootfile and reboots
cl_init always logs onto the server using default login name autoinst.
The user can set environment variable dllogin in the PROM to change the
login name. For example, typing
setenv dllogin root
at PROM manual mode causes the diskless workstation to log onto the
server using root.
When using default login autoinst, all messages before the inst(1M) menu
are filtered. If there is a need for examining the login messages, such
as for debugging purposes, it is possible to disable this feature by
typing two or more escape characters before entering the password.
cl_init is to be used only by the diskless client installation package.
If cl_init is invoked on a shell command line, the shell hangs. If the
hung shell receives an INTR signal, the system is shut down silently.
