I wanna try Portage

[spanishbizarro]

I'm thinking of starting a new installation and to only use portage. What would you recommend me (besides of reading the portage guide)? Should I better install gentoo?

[throdon]

I suggest that you start with the most minimalist Sabayon ISO you can handle.

I also suggest you have the Gentoo handbook and perhaps Linux sea http://swift.siphos.be/linux_sea/ Bookmarked and Read the DAMN things, they are there for a reason and people put a lot of hard work into it.

If and when you start monitoring the Gentoo forums make sure you let them know you are using Sabayon and post in the unsupported software threads. I used a Sabayon live DVD to install gentoo once and they thought it was a Sabayon support question. Be clear in what you post over there.

Is it possible to use only Portage in Sabayon, but not easy or raccomended.

At first, you SHOULD edit the file /etc/entropy/client.conf and in the line that have pseudodowngrades you substitute disable by enable.

If you dont make this,the Entropy will be downgrade the packages, instead of upgrades.

also, read and learn from the net and here, in the Sabayon Forum, wow to edit /etc/make.conf. Without editing make.conf, Portage itself is not advantageous.

Even when you not use it, does not remove Entropy.

You may try other Distros, that are Gentoo like,but not use Entropy, only Portage.You may try using tthe German Linux Toorox, ou the Russian Distro Calculate. They are easy to install Gentoos.

Hi,
I'm thinking about safely mixing Entropy and Portage, because of different reasons:

1. When installing Firefox and Tb a plenty of language packs have been installed, too. The versions are already outdated. For these programs I always want the most actual (stable) version as soon as they are released.
2. I need a program that's not in the repos for Entropy but in an overlay for portage which is among those I can see with:

Code: Select all

# layman -L

3. I need to re-configurere gcc with options "--enable-languages=c,c++,go" and "--with-arch-32=i586" and re-compile+re-install it. Only then I can use the gccgo compiler.
4. Later I would like to re-compile KDE with the "-march=amd64" option.

When reading HOWTO:_Safely_mix_Entropy_and_Portage I asked myself: Is gcc a 'system package'? Linux runs without it and Entropy doesn't use it, I would suppose... Do you think/know that building gcc with Portage will be problematic, even when following the rules from the HOWTO?

Additional Problem:

Code: Select all

# layman -l

doesn't show the overlay 'sabayon' as active. Would

Code: Select all

# layman -a sabayon

be the right solution for that?

@wolfden
Thanks for the link.
I also read the thead Looking for a good 3D chess [Solved] and think you meant that I should install both overlays: sabayon and sabayon.distro .

Please help me to understand the technical principle that's behind:

Portage overlays are custom Portage trees that contain packages not found in, or different from the packages in, the main Portage tree.

that's quoted from HOWTO:_Install_Packages_on_Sabayon_/_The_Complete_Portage_Guide.

..., make sure you have "sabayon" in your overlays

that's from HOWTO:_Safely_mix_Entropy_and_Portage. "sabayon.distro", too, if I understood you well.

Assuming that I want to install software, let's say DreamChess which has an ebuild in the Portage Sunrise overlay. WHY is it so important then, that the overlays "sabayon" and "sabayon.distro" are also installed?

[wolfden]

You don't have to have any overlay, you can add and drop overlays as you need to. It all depends on what you want or need.

When decided to move to Portage only, maybe it's better to leave "sabayon-distro overlay" alone for now.
Later you can decide whether to add that overlay or not.
FIRST of all take a good notice on how Portage works, and how to use it.
Gentoo and Sabayon Wiki is your friend here,
but with a little searching, the Web is full of sources to help you with that. Even Youtube provides tutorials on how to use Portage.
Listen very carefully at the messages Portage gives you., Most commonly made mistake is that people DON'T read Portage messages., and since we're using the unstable/alpha Portage tree, do not ever, update Portage when it tells you there is a update available., 'cause then you actually downgrading.
If, when updating with Portage a new "sys-apps/portage" is marked for upgrade, be sure to check if it's a alpha release.

Indeed you should start with the most minimalistic Sabayon ISO you can handle.
Spinbase, or CoreCDX for example.
After installation, first thing is to make Sabayon ready for Portage.
Edit your "make.conf"
a example for a portage only make.conf can be found here:
http://pastebin.sabayon.org/pastie/12119
*note*
Under section "## PORTAGE CONFIG ##",
PORTAGE_ELOG_CLASSES="warn error log"
PORTAGE_ELOG_SYSTEM="save"
are set. This feature will create warning/error messages for each package, but you first have to create:

Code: Select all

mkdir /var/log/portage/elog

When done installing and configuring, you might as well want to recompile your system:
either with:

Code: Select all

emerge -aveND @world --keep-going
