How to reduce (or optimize) size of recently built LFS?

Question

As the title shows, I've recently built an LFS (version 8.3), with jhalfs. So with du -h, the size of the whole partition is about 4.5 GB (I've already deleted all the files in /sources).

Executing this command that shows what are the big files in the system : du -a / | sort -n -r | head -n 10 , shows this result :

Does anyone know how can I optimize and reduce my partition (what files / packages /or repertories to erase) without breaking the OS ? The goal is reaching an operating system that turns around 400 or 300 MB. Thank you

Aside from removing /tools and maybe also docs (/usr/share/doc, /usr/share/man) you can also strip debugging symbols from all the libraries and executables. This is done using strip(1) utility; detailed instructions can be found in the LFS book, section "Stripping Again".
