Mine is close to that. I still had a working libc, but the dynamic library for C++ programs wouldn’t load, so most of the Gentoo tools and several other things I expected simply crashed on startup.
Found enough working programs to get the library restored and remove the bad arch flags from my configuration to start another emerge world.
After that, I was pretty confident that I could run Linux at least as confidently as I had previously run WinNT 4.
