Hi!
You do not address the different benefits, this new system has, compared to rolling back with btrfs, or bcachefs.
What is the benefit of implementing a new package manager, when configuration files, media and other parts, that are not covered by the package manager, can not be restored?
And why is it worth the effort, when a seemingly sufficent solution already exists?
It might be worth, mentioning this on the homepage, since I am sure, this is one of the first questions on everybodys mind.
