using md-mounted ISO as NFS root for PXE booting and installing
Hello.
I have 6.1-STABLE FreeBSD box I want to use as network
boot and install server for PXE clients.
At this moment I'm experimenting with 4.11-RELEASE-i386-disc1-gnome.iso
and 6.2-RC2-i386-disc1.iso images.
Related DHCP config section is:
host netboot {
hardware ethernet 00:04:**;
fixed-address 192.168.13.2;
next-server 192.168.13.1;
filename "boot/pxeboot";
option root-path "192.168.13.1:/mnt/netboot";
}
Exports (/etc/exports):
/mnt/netboot -network 192.168.13 -mask 255.255.255.
TFTP is running under xinetd with "-l /mnt/netboot" options.
Then I mount ISO image to /mnt/netboot with mdconfig and mount_cd9660,
and boot PXE client.
All is fine if we are booting into 4.11 (root mounted from MFS,
sysintall runs and we able to install OS to local disks via NFS).
But in case of 6.2-RC2 root mounted from NFS, not MFS:
192.168.13.1:/mnt/netboot on / (nfs)
devfs on /dev (devfs, local)
/dev/md1 on /var (ufs, local)
/dev/md2 on /tmp (ufs, local)
and I can see just another "Amnesiac" system w/o root password etc.
Where is my mistake?
I attached dmesg output for 6.2-RC2 boot to this letter.

Of course, you have to copy the boot/ directory out of cd. Regards, Rong-En Fan
