Hi everyone,

I'd like to announce a new subproject of Hardened Gentoo, Hardened musl 
[1].  musl is a new C standard library, optimized for embedded systems.  
It is "lightweight, fast, simple, free, and strives to be correct in the 
sense of standards-conformance and safety."  [2] Like its sister 
subproject, Hardened uClibc [3], this project focuses on porting both 
userland and kernel hardening to musl based systems for a variety of 
architectures, treating musl as a drop in alternative to glibc.  The 
releases are not "embedded" in the sense that most userland utilities 
are provided by busybox; rather, we make use of coreutils, util-linux, 
and other typical GNU utilities that you'd find on any regular Gentoo 
system.

The release images are stage3 tarballs built using catalyst and our 
automation scripts [4].  Unlike the uClibc project where most packages 
"just build", musl's adherence to standards means that many packages 
need some minor patching. These are kept on our hardened-dev overlay in 
the musl branch [5].

This is work in progress.  The following table gives a brief summary of 
the current state of affairs:

Arch            Subarch            ABI(s) Flavors                  Status
amd64        Generic             default 64-bit hardened/vanilla   stage3
arm             armv7a             eabi hardened/vanilla   stage3
mips            mips32r2          o32 vanilla                  <in progress>
mips            mipsel3             o32 vanilla                  stage3
x86             i686                  default 32-bit vanilla             
      stage3


These are available on the mirrors at ${MIRROR}/expiermental/${ARCH}/musl.
