Depends on what version of Jaguar you are using:

10.2.0=6.0
10.2.1=6.1
10.2.2=6.2
10.2.3=6.3
10.2.4=6.4

open up a terminal and type "uname -srp"
hmmm.... I need something clever here....

Darwin integrates a number of technologies, most importantly Mach 3.0, operating-system services based on 4.4BSD (Berkeley Software Distribution), high-performance networking facilities, and support for multiple integrated file systems.

Well, It sounds like Jaguar is based on BSD 4.4. I'd assume Panther will be based on a more recent version of BSD, since 4.7 is out already. Of course, I have no clue which version Apple will use. They have to pick a version to work with while there is enough time to get the work done, so the choice has probably already been made.

FreeBSD is actually at version 5.0.

<a href="http://www.freebsd.org/releases/5.0R/announce.html" target="_blank">FreeBSD 5.0 Release Announcement</a>

Let's hope that Apple had access to a pre-release of 5.0 and has built 10.3 on top of it.

Though it's interesting that FreeBSD has not been officially ported to a PowerPC processor yet. See link.

I think it would be in their best interests to work with stable code instead of scraping together an OS at the last minute from a collection of unproven code.

I don't know if they could realistically have enough time if they were using the BSD 5.0 code, and I don't know if it's really that much better than 4.7 to be worth the risks.

(risks being buggy code and/or running out of time)

Jaguar's kernel and personality are equivalent to that of Darwin 6.x.
