Re: [9fans] micro vs monolithic kernels

the nvram isn't important.  it will prompt for the values if necessary
and that's the easiest way to check that it is correctly booting the cpu server
kernel not the terminal kernel.  once that's going you can worry about setting
up the nvram.

i set a cpu/auth system up recently (without a separate file server).
i think this is what i did:

0. build /lib/ndb/local correctly; in many ways, the hard part.  you need to get
    the ipmask= and ipsubmask= and ip-net= set up to describe your network correctly.
    include proto=il in the entry for each plan 9 machine.
    include default auth= and fs= entries in the network or subnet entries.
1. cd /sys/src/9/pc; mk 'CONF=pccpudisk' install
2. 9fat: ; cp /386/9pccpudisk /n/9fat/9pccpudisk
3. change /n/9fat/plan9.ini, bootfile=sdC0!9fat!9pccpudisk  (replacing sdC0 by your disc name)
4. make sure /lib/ndb/auth contains

hostid=bootes
	uid=!sys uid=!adm uid=*

  this lets the cpu server believe that the auth server can vouch for others as described

5. cd /rc/bin/service; mv il566 _il566; mv tcp567 _tcp567
6. cd /rc/bin/service.auth; ensure the following contents
	tcp567:
		#!/bin/rc
		/bin/auth/auth.srv -d $3
	il566:
		#!/bin/rc
		/bin/auth/auth.srv -d $3
	chmod a+rx tcp567 il566
7. modify /rc/bin/cpurc to uncomment the lines that are commented-out:

	# uncomment the following for booting other systems
	ip/dhcpd
	ip/tftpd

	# services available to networks (remove -t /rc/bin/service.auth
	# if this isn't an auth server)
	auth/keyfs -m /mnt/keys /adm/keys
	aux/listen -q -d /rc/bin/service -t /rc/bin/service.auth il
	aux/listen -q -d /rc/bin/service -t /rc/bin/service.auth tcp
	auth/cron

   you can add a switch($sysname){ ... } to select different cpu server services
   if you've got more than one and only one is acting as auth server and file server.

8. if you're not setting up a separate file server (using the /sys/src/fs kernel) but are
   serving files from a kfs partition on the cpu/auth server, then further do
	8a.  cd /rc/bin/service; mv il17008 _il17008
	8b.  in /rc/bin/cpurc above, after starting auth/keyfs and before aux/listen do
		disk/kfscmd listen
