After several similar questions about this subject over the years, I
should really wish that Sun had created an official How-to about this,
but sorry no, they didn't as long as know.
Scenario:
On a Sparc Solaris 7 server I have re-installed Solaris 7 Enduser OS
service for a good old SS1 (sun4c) diskless (52 Mb memory) client, using
the Adminsuite 2.3/Solstice Hostmanager tool.
In addition to work in 'pure X terminal mode' with remote dtlogin to the
Solaris/app-server, the SS1 client is only requiered to handle a tablet
(digitizer) input connected to its local serial port.
On the clients filesystem I have already disabled the local CDE startup.
Next I have replaced the 'ttymon' entry in the clients /etc/inittab with
'/usr/openwin/bin/Xsun -query', so that a remote CDE login from a
networked server is displayed directly after the client booting.
Problem:
What I now need is practical guidelines how to further trim the Solaris
setup for the client, to speed up its boot process and dedicate most of
its limited resources for the X terminal work.
That is, which of and how to disable unecessary startup scripts,
services and daemons (fx printer, volum manager, sendmail and more)?
Some years ago I got a reply that most of if not all of the rc scripts,
except that for the network, really were unnecessary, and that booting
to run level 1 (singleuser) could be sufficient for a pure X terminal
mode. But I'm not sure regarding the serial port (tablet) support.
If this is really possible, how to do it?
TIA/Terje
