:Seems like diskless clients would have to have separate kernels with
:the "option BOOTP" while any servers must omit this option.

:How do you keep them separate? or am I missing something fundamental?

:Thanks.
You can compile pxeboot with the LOADER_TFTP_SUPPORT=YES option.
Add LOADER_TFTP_SUPPORT=YES to your /etc/make.conf and recompile
/usr/src/sys/boot (make clean; make obj; make; make install from
within /usr/src/sys/boot).
If you do this pxeboot will attempt to load the kernel via TFTP
instead of via NFS. You then put your kernel in /tftpboot right along
side a copy of pxeboot.
This allows you to netboot a different kernel then the one in the
server's root directory.
:PS: could you show me your dhcpd.conf so I can see how you're
: specifying your root filesystem? Mine's currently:
: option root-path "192.168.255.185:/";
subnet 216.240.41.0 netmask 255.255.255.192 {
range ...;
server-name "apollo.backplane.com";
option subnet-mask 255.255.255.192;
option domain-name-servers 216.240.41.2;
option domain-name "backplane.com";
option broadcast-address 216.240.41.63;
option routers 216.240.41.15;
group {
filename "pxeboot";
option root-path "216.240.41.2:/";
host net1 {
# Alternative server to boot -current
# option root-path "216.240.41.12:/";
# next-server 216.240.41.12;
hardware ethernet ...;
}
host net2 {
hardware ethernet ...;
}
...
}
}
