Hi,
First of all, thank you for using isboot.
The basic problem with isboot is that it only works with the old iSCSI
initiator, which is now marked obsolete. AFAIK there is no ready solution
It's started in FreeBSD 7.1.
I plan to use initiator functions at 2010.
However, I didn't know how to access it.
For more, first post on blog(Japanese):
http://shell.peach.ne.jp/aoyama/archives/1179
Now isboot has own limited builtin initiator to handle login sequence.
isboot will continue to use it instead of switching to iSCSI initiator.
So I think current problem is header file (structure in it) only.
You don't need load iscsi_initiator.ko even if you use FreeBSD 10.
I have removed these header files in 0.2.11 release.
It is not so difficult compared to that to rewrite the code.
Of course, I should replace the code later...

You can boot/install with the demo and empty disk. (see attached N4F/istgt
config image)
build test(not jail host):
8.4, 9.3, 10.2, 11-current.
boot/install test:
NAS4Free 10.2.0.2(istgt) + FreeBSD 10.2 memstick + VBox + iPXE(iso).

+1. I have used this module in the past and it is extremely useful. Thanks for the pointer, I
wasn’t aware it had been updated for FreeBSD 10.x so recently. I’ve also wondered why this
is not part of FreeBSD by default.
Aoyama-san, do you have any objection to this code being included in FreeBSD? If not, can you
formally assign it a BSD or other friendly license? Thank you again for the work!
Trasz (or anyone), is there other work to support iSCSI booting and/or IBFT on FreeBSD?
Anything else isboot might conflict with? Any problems with integrating the code or with the
code itself?
The basic problem with isboot is that it only works with the old iSCSI
initiator, which is now marked obsolete. AFAIK there is no ready solution
that works with the new one - however, it should be possible to use upcoming
reroot support to achieve this: boot with a temporary rootfs, mounted from
a ramdisk preloaded by loader(8), setup an iSCSI session, and then replace
the temporary rootfs with the real one, mounted over iSCSI.
