I give up!
I cannot understand why my diskless system is not working.
I'm working with FreeBSD4.5-RELEASE.

This is what I have done:

1. I have a free slice in my hard disk [slice 3].
   I made a new file system in it with  /stand/sysinstall
   took the slide and mounted it on /diskless

	cd /dev
	./MAKEDEV ad0s3c
	newfs /dev/ad0s3c
	mkdir /diskless
	mount /dev/ad0s3c /diskless
	mkdir /diskless/rootfs

2. With /stand/sysinstall I loaded bin, crypto and sys
   distributions in it.

3. I installed and configured isc-dhcp3-3.0.1.r4
   the /usr/local/etc/dhcpd.conf files is:


================
ddns-update-style none;
option domain-name "esfm.ipn.mx";
option domain-name-servers 148.204.102.3;

default-lease-time 600;
max-lease-time 7200;

subnet 192.168.123.0 netmask 255.255.255.0 {
   option routers  192.168.123.254;
   host lucia {
     hardware ethernet 00:01:03:be:a4:c5;
     fixed-address 192.168.123.176;
     filename "/tftpboot/kernel";
     option root-path "192.168.123.112:/diskless/rootfs";
   }
}
==============


and made dhcpd.leases data base:

      touch /var/db/dhcpd.leases

dhcp server is working, a neighbour machine took its IP
properly.


4. I enabled tftpd in /etc/inetd, the configuration line says:

tftp dgram udp wait nobody  /usr/libexec/tftpd tftpd /tftpboot

I restarted inetd:

	killall -HUP inetd

tftpd is working properly because I can transfer files from
my server by tftp.


5. I recompiled and installed my diskless kernel.  I believe
that my configuration file is too large to include in this
messages but it configures a very simple kernel including:

---
options   BOOTP           # Use BOOTP to obtain IP address/hostname
options   BOOTP_NFSROOT   # NFS mount root filesystem using BOOTP info
options   BOOTP_NFSV3     # Use NFS v3 to NFS mount root
options   BOOTP_COMPAT    # Workaround for broken bootp daemons.
---

to install my kernel:

	chroot /diskless/rootfs
	cd /sys/i386/compile/diskless
	make install
	exit

it worked fine. Then, I copied my kernel to /tftpboot

	cp /diskless/rootfs/kernel /tftpboot

6. I made a simple /etc/fstab file:

# Device                Mountpoint      FStype  Options         Dump    Pass#
192.168.123.112         /               nfs     rw              1       1

7. I compiled /usr/port/net/etherboot and, I am using a booting
diskette that I made:

	cat floppyload.bin.pre eepro100.rom > /dev/fd0

it works fine, recognizes my ethernet card and transfer my kernel.

8. I know I must create /conf/default/etc with a copy of my
   /etc directory,

BUT.........

When the kernel is loaded, it begins to check my diskless computer.
Finally it sends a "DHCP discovery packet" to find the NFS
directory that will be used as root directory.

It finds it correctly saying:

	NFS ROOT: 192.168.123.112:/diskless/root


and it complains saying that cannot find "init" in a list of directories.

Now, if I stop the kernel before it takes the control of my diskless
box, it has already mounted 192.168.123.112:/diskless/root and the files
can be listed.


I do not understand what is happening, it seems that my kernel is not
able to load its root file system and it cannot find init in it.


The same procedure [with the only difference in the dhcpd version]
is working perfectly in a FreeBSD 4.3 server [/client].

Do you have any idea of what I am doing wrong?
Any help will be appreciated.

	Eduardo.
