I don't quite understand the whole point of this patch. I have no
"special" loader.conf files and the diskless test machine boots just fine.
I suppose dhcp server sends vital information which is understood by pxeboot.
On the dhcp/tftp/nfs server:
> cat amd64/boot/loader.conf
loader_logo="beastie"
snd_hda_load="YES"
ahci_load="YES"
vboxdrv_load="YES"
> cat amd64/conf/base/etc/fstab
md /tmp mfs -s=128m,rw 0 0
linprocfs /compat/linux/proc linprocfs rw 0 0
> ls /tftpboot/
pxeboot
> tail -20 /usr/local/etc/dhcpd.conf
#}
subnet X.X.X.0 netmask 255.255.255.0 {
}
group {
next-server HOSTNAME;
filename "pxeboot";
option root-path "HOSTNAME:/home/jails/amd64";
host HOST1 {
fixed-address Y.Y.Y.Y;
hardware ethernet xx:xx:xx:xx:xx:xx;
}
host HOST2 {
fixed-address Z.Z.Z.Z;
hardware ethernet yy:yy:yy:yy:yy:yy;
