New profiles, fresh install?

I am about to install Gentoo onto a new system. Are the new profiles, GCC, libtool, binutils, etc already updated or do I get to run through the process before I do anything?

I'm not sure, but I think no because in latest stage3 you can select also profile 13 and for this the related tool must not be compiled with pie, but I could be wrong.

Not that it takes long to switch to 17 that early in the process.

OK, so I get into my chroot, sync up portage, rebuild world, go through that process of selecting the new profile, rebuilding GCC, libtool, and binutils, then do emerge -e, then proceed as normal?

Agree with charles17. Rebuilding world before switching profiles is completely unnecessary. It might save you a second on the second compile time but I don't think that is worth the hour or so rebuilding would take.

Alright. I'll do it that way then. I assume that once this new profile setup, GCC6, and this other stuff is stabilized it will be in the stage3 tarball so we won't have to build it this way?

I'm sure the stages will catch up quick enough if they have not already. Problem is that your timing on this kind of sucks.

There hasn't been a chance for the changes to ripple through the build process. Fortunately, It shouldn't slow you down too much. Doing an emerge -e on a new install is generally a good idea.

Just yesterday I set up an fresh stage 3 on my build host for the 17.0 profile. I set the profile before I emerged anything, and then rebuilt @system. That and almost everything else went pretty smoothly.

One word to the wise: if you do as I typically do--set up make.conf and package.* from an older system--be sure to update your make.conf before emerging anything! In this case, my older setup had python3_4 in the PYTHON_TARGETS. The stage 3 tarballs now have python 3.5. If PYTHON_TARGETS has versions of python 3.* before 3.5 you'll end up with an unnecessary emerge of the older python version and strange problems in emerging packages line net-dns/bind. I found this out the hard way. Save yourself hours of "fun" by taking this precaution first.

On the stage3 @system is exactly the same as @world so either one will do.

Since there are various stage3 archives available, why isn't there stage3 archive named for example stage3 profile17 (or something like that) ?
That would avoid rebuilding gcc and @system.
Or make it like that as default stage3 archive and make current one available as additional stage3 download (profile 13), if there is still a need for that.
