Copying the source code tree

I need a certain source tree on my RPi3 as the FreeBSD aarch64 image has no source tree included.
Unfortunately all that available is FreeBSD 12.
The problem I have is when I fetch the /base/head source code it has already advanced in revision beyond my very recent RPi3 download.
Not much differences I am sure, but I want to compile kernel only, not the entire world.
I also understand that I need to keep kernel and world in sync.
I could probably recompile the kernel with the slightly newer source, but I really don't want to take the chance.

So how to get a certain revision of source code. r326056 in particular.
My path went like this. Download the same revision amd64 memstick installer, install and copy the source tree from there to the RPi3.

So the crux of my question is:
Are there any file/directory permissions/ownership or other snafu's that would make a simple copying of source to another platform not work?
I could tar and copy if so needed. Maybe even untar the memstick src.txz file.

Thanks for the help and any pointers appreciated.
I am sorry for discussing /head related issues.
 
If you already has it checked, I guess you need this:

svn up -r 326056

If not:

svn checkout -r 326056 url://etc.

or

svn checkout url://etc./path@326056
 
Ok Thanks so I will try this next:
svnlite checkout -r 326056 https://svn.freebsd.org/base/head /usr/src

Nope, there's nothing special about the /usr/src/ directory and can easily be copied or NFS shared with other machines. It doesn't even need to be writable, you can share it read-only with NFS if you want. When building /usr/obj (or wherever MAKEOBJDIRPREFIX is pointing to) is used for the intermediate files.
 
SVN is the go to tool for that. Use svnlite(1): svnlite co https://svn.freebsd.org/base/releng/11.1 /usr/src for example.
 
Anything wrong with this?
Code: 
cd /
fetch http://ftp.freebsd.org/pub/FreeBSD/releases/amd64/11.0-RELEASE/src.txz
tar zxf src.txz
 
Using 11.0-RELEASE is wrong since it's not supported anymore on 2017-11-30.

Besides that it's ok if you do a freebsd-update(8) run afterwards or apply all errata and security patches since release yourself manually.
