5.4.1. Installation of Cross Binutils -Permission Denied

In a previous chapter the following was given:
chown -v lfs $LFS/tools
chown -v lfs $LFS/sources

But root still owns $LFS

So now when I enter:
mkdir -v ../binutils-build

I get Permission Denied.

Should lfs also own $LFS?

And shouldn't that have been:

chown -v lfs $LFS/sources -R

Your mkdir command should be done when you are in the binutils src dir, in effect you are creating $LFS/sources/binutils-build
So $LFS need not be owned by lfs

Hope the makes sense,
To clarify that a little more, each chapter assumes you have done

untar xyz.tar.bz2
cd xyz

the ../ is the parent dir of the current

....

Just seen your latest post come in,, the -R is the recursive flag, but since that dir has just been created it shouldn't have anything in it, still no harm adding that

Yes, that makes sence, and what I expected, except 
the book says "The Binutils documentation recommends 
building Binutils outside of the source directory in 
a dedicated build directory".
Now I see what it means. It's referring to the 
Binutils source directory not the $LFS/source 
directory. 
So yes, it would be created then in 
$LFS/sources/binutils-build
I understand now. Thanks.

I think that it's probably better not to use the -R, so that the sources 
don't get accidentally erased when doing an uncompress command, as some 
of those commands delete the compressed files after extracting.

I had asked if it should be -R because I did not know that a root owned 
compressed file could be uncompressed, but it makes since that you can 
uncompress it since you can read it.

So everything is going good.

Thanks,
