Indy NFS-root mini installation manual.

["Chris Tilly" <chris_tilly@hotmail.com>]

This describes a root-nfs install of woody on an Indy. I needed several 
pieces of info that weren't in one place. I also ran into problems getting 
around the nfs locking promlem for a root install. Hope this proves usefull 
for someone.

the setup;
dhcp, tftp server running redhat 7.2 @ 192.168.0.1
/tftpboot contains tftpboot.img
/tftpboot/indiana is a clean drive mounted for the install. indiana is going 
to be the indys hostname.
/mnt/debmips is the debian install disk 1 image mounted with;
#mount -t iso9660 -o loop /path-to-image /mnt/debmips

indy at 192.168.0.5 with the following prom settings;

SystemPartition bootp():
OSLoader	vmlinux
OSLoadPartition	/dev/nfs
OSLoadOptions   ip=bootp

these settings work for install and nfs-root so I think the OSLoader env 
gets overwritten by the dhcpd.conf setting.

I'm using dhcp-3.0. There were several problems with earlier versions 
including having to 'unsetenv netaddr' in the prom for every boot and 
locking problems. Upgrade.

My /etc/dhcpd.conf:

ddns-update-style ad-hoc;
subnet 66.183.189.0 netmask 255.255.255.0 {}
subnet 192.168.0.0 netmask 255.255.255.0 {}

host indiana{
	always-reply-rfc1048 on;
	hardware ethernet 08:00:69:06:e7:9e;
	fixed-address 192.168.0.5;
	option host-name "indiana";
	option domain-name-servers 209.53.4.150;
	option routers 192.168.0.1;
	filename "tftpboot.img";
}

my /etc/xinit.d/tftp:

service tftp
{
 socket_type		= dgram
 protocol		= udp
 wait			= yes
 user			= root
 server		= /usr/sbin/in.tftpd
 server_args		= -l -s /tftpboot
 disable		= no
}

my /etc/exports;

/tftpboot/indiana 192.168.0.5(rw,no_root_squash)
/tftpboot 192.168.0.5(rw,no_root_squash)
/mnt/debmips 192.168.0.5(ro)

I have /tftpboot/indiana AND /tftpboot in there because I seem to remember 
exports don't span filesystems. Doesn't hurt, anyway.


boot the indy. On an earlier version of dhcpd the only way i could start a 
boot was to select "run diagnostics" from the prom menu. This went away when 
I upgraded to 3.0

do the config, including hostname and network setup, up to  'mount 
previously init partition'

select 'execute shell'


#mount -t nfs -o nolock 192.168.0.1:/tftpboot/indiana /target
#exit

continue with install up to (not including) 'install base packages', execute 
a shell.

run this script (from section 6.8.1 of deb-mips installation manual, 
modified):

#!/bin/sh
mount -t nfs -o nolock 192.168.0.1:/mnt/debmips /instmnt
cd /target
mkdir x
cd x
for i in g/glibc/libc6 t/tcp-wrappers/libwrap0 p/portmap/portmap 
n/nfs-utils/nfs-common
do
  ar -x /instmnt/pool/main/$i''_*.deb
  zcat data.tar.gz | tar xv
done
umount /instmnt



#umount /target
#mkdir /temp
#mount -t nfs -o nolock 192.168.0.1:/tftpboot/indiana /temp

run this script;

mkdir -p /var/lib/nfs
cd /temp/x
for i in portmap rpc.statd
do
 LD_LIBRARY_PATH=lib sbin/$i
done

#mount -t nfs 192.168.0.1:/tftpboot/indiana /target

now 'mount' should show the lock option for /target. At this point you 
should be able to continue with the install.

The install program kept hanging for me on the 'trying to detemine what's 
next' screen at this point. A ctrl-C restarted it.

Now we should be at 'reboot the system'

on the server;

in /etc/xinitd/tftp change server_args to;

server_args = -l -s /tftpboot/indiana


in /etc/dhcpd.conf change filename to;

filename "vmlinux";

restart xinit and dhcpd

now we should be able to boot into our system. The installation manual says 
the provided kernel doesn't have CONFIG_ROOT_NFS, in fact it does. Any 
guesses on how long it would have taken me to install gcc and compile a 
kernel in a chroot enviroment on a 48 meg indy 4000sc/100Mhz with no swap?
