upgrade from 3.4 to latest

[diwakar09]

Hi,
How to upgrade sabayon 3.4 to latest i.e 4.1. I have an installation of sabayon, Now I have decided to upgrade it to 4.1. And I don't have any 4.1 CD. How to do it from the terminal,some thing like (apt-get|yum|yast upgrade).
I am not familiar with sabayon package management system.

Dude I think you are out of luck.
get one shipped if you can't DL Sabayon 4.1 GNOME/KDE.
I believe they are incompatable(too many breakages)
save what is on your Hard drive and install 4.1 then reintroduce your saved files.

3.4 is portage based and VERY OLD. It would be possible in theory to upgrade, but it would be alot of effort and you would probeblly end up with a non working system.

I would reccomend a backup and fresh install then recopying your personal files back into the new install

Ok, I will follow the same thing.
Some of my friend told me 2 try sabayon, and he had version 3.4. On net I found sabayon has released 4.1. So from there this upgrade thing start.
can you tell me how to install a application using sabayon repository system. I have prior experience on centos and suse. For them i have used yast and yum. Is there any such simillar command in sabayon.

Thanks

Sabayon Linux is a customised version of Gentoo Linux. It has two off-the-shelf package managers: Gentoo's Portage plus Sabayon Linux's very own Entropy. You can read all about both of them -- including the commands -- in the Sabayon Linux Wiki (see the link at the top of this page). There are various third-party GUIs for Portage, one of which is Portato. And Entropy has the Spritz GUI for those who like a GUI. Again, you can read all about it in the SL Wiki, which also has an installation tour guide.

Portage downloads source code onto your HDD and compiles it. Entropy downloads pre-compiled ('binary') packages onto your HDD. So Entropy is like the package managers for the vast majority of Linux distributions (including the two you mentioned). Binary packages may not be optimised for your specific hardware and software environment but, to be honest, in most cases you don't notice a difference.

Portage is more complicated and means that, if you do not know what you are doing, you can break your installation more easily. Entropy is simpler to use and thus more newcomer-friendly.

Both package managers allow you to keep your installation ('world') up to date: the so-called 'rolling release' system. With Entropy this is particularly easy.
