Here’s interesting. The Sabayon team have introduces a sabayon-weekly Entropy repository that will only be updates once a week – on Sunday. The aim is to offer a painless way to downgrade packages.
I’m not in a position to play around with this just yet, but am intending to take a look at it when I get home this evening.
I am guessing, however, that you would need to put a little thought into when you run your normal upgrades but – theoretically – anything you upgrade between Monday and Saturday can now be easily rolled back to the state it was in on Sunday.
I’m looking forward to having a play with this.
Update
Well that was easy.
Adding the weekly repository to /etc/entropy/repositories.conf is a simple copy and paste
Then I started up Sulphur to see if everything looked okay and it told me that I needed to download the repository before I could use it.
One click later…
Now I just need to find an excuse to downgrade something.
