genkernel package installs source codes into /usr/share/genkernel/disfiles directory.
This directory for sys-kernel/genkernel-4.2.6-r2 has ~174 MiB:

All this sources - are the same, as in DISTDIR="/var/cache/distfiles" (from make.conf).
Dublicates of files in /usr/share/genkernel/distfiles and in DISTDIR="/var/cache/distfiles".
Source code must be stored only in single copy under $DISTDIR (from make.conf) directory.
I rebuild my kernel after normal system update. But have troubles in genkernel, which needs to rebuild LLVM2 package, but build fails with an error:
> ld.lld: error: unable to find library -l:libunwind.a
My system have sys-fs/lvm2-2.03.14, but genkernel rebuild initramfs with 2.2.02.188 version.
At now, portage does not have 2.2.02.188 version, but have 2.02.188-r2 (current stable version).
genkernel build initramfs exactly with llvm-2.2.02.188 version, even main system have 2.02.188-r2 or 2.03.14 versions.
I think, that this error may be resolved by switching genkernel to use newest version of lvm package.
1) Remove source code archives from genkernel program directories.
2) Use packages, which needs for build initramfs, directly from portage tree, not by local copy.
- save disk space$
- build initramfs without errors from old and bugged versions of required packages.
