Hi list!
I would like to switch to hardened gentoo from Adamantix. I need a linux
that has PaX, SSP and RSBAC at least. And support, QA. That's what is
missing from Adamantix.
So this is the first time I try to install gentoo, by the book, and it
fails. Since I have no experience with gentoo I write here what I did,
so you can tell me if I have missed a step, or made some other mistake.
I am sorry, but it is a little bit long.
Booted from CD, have net, partitioned, formatted, mounted, downloaded

>>> sys-devel/gcc-3.4.6-r2 merged.
Does this mean that the new, SSP patched gcc is installed, but not in
use at this point?
If it is so, isn't it a problem, that binutils and libc is compiled with
the old gcc?
And why is this version 3.4.6?
I have expected to see the same version of gcc that I already had (from
stage3 I suppose), which is 4.1.1, recompiled with SSP, and possibly
other patches, and the new hardened version to replace the current one.
Why does emerge give me an older version? Is this normal?
And it seems that the method written in
http://www.gentoo.org/proj/en/hardened/hardenedfaq.xml#hardenedprofile
does not work.
emerge downloads binutils, compiles for about half an hour, unmerges
original, merges binutils-2.16.1-r3
emerging sys-libs/glibc-2.3.6-r5 to /
downloads, then:

So, emerging libc has failed. I thought that when I switch to the hardened
profile, it only has to recompile the same version that I already have.
But it seems that it tries an older version? Just as it did with gcc.
Why?
So what do I do now?
Do I have to manually switch to the hardened gcc? Then I have to recompile
binutils, as it was compiled with the unhardened gcc. How do I emerge the libc?
Cheers,
Gabor
