i have 4 Sabayon installations. I use it since the version 3.4F, 6 or 7 years ago.
My main installation have almost 4 years, it was originally a 5.2 version. "Rolled" since this version. it is in version 14. Limbo Repository.
My other installations:
one, originally was a version 6, it is 32 bits, in a old computer, it was upgraded until the version 9. No more upgraded due to the old NVIDIA board. I use sometimes, in the version 9 itself.
other, was originally an Sabayon 6, upgraded until, now, 14 version
here, in the university, my Sabayon was installed from a 10 version live DVD, rolled until 14, Limbo Repository.
No special care, except not use Portage in it, at least for the begginers. used without care, Portage may break Sabayon easily.
upgrade normally using entropy or rigo. when you have a problematic video board, speciallyy ATI boards, not upgrade the kernel, because each new kernel requires a new video driver.
Sabayon needs some expertise. When i was a Noob in Sabayon, i lost 6 installations!
Begginers re-install often, but when you know how sabayon works, it is even possible to mix the package installers and use both Entropy and Portage.
Sometimes, after upgrades, something is broken, but when you have some expertise in using sabayon, you will solve the problems.
