I'm not sure what you mean by:
"Tumbleweed is designed to be based off of something, not to roll forever".
It's a rolling release of opensuse. It's been rolling for years now.
I found opensuse updates the kernel almost as soon as new ones are released. KDE updates take longer to reach the repos. Sabayon was just the opposite and took much longer to update the kernel, but KDE was updated almost immediately. At least with mostly open source, I also have Flash, Tumbleweed has worked well for me. Sabayon not so much, though if you want the newest video driver blobs and kernel it's the only option.
Nope. Our ethos is of user choice; pragmatism is what we do. Even our more churlish developers aren't so spiteful as to attempt to dictate what choices you have. Skype 4 is already in the Portage tree as of yesterday (that's the earliest I noticed it). Heck, we even have people trying to get systemd working, despite having OpenRC already.
Suffice to say, if they're looking to commit to rolling release, they could do far worse than looking to Gentoo for inspiration (or just rebase on us; we could absorb their patch flow easily).
I hope they do not go the Rolling route. I have yet to see a rolling distro with good QA.
However, if they pull off a well working rolling release distro, I'll end up being fine with it.
Archlinux had it in the official repos yesterday(fairly early in the day), as well.... There is definitely something to be said for distros that don't try to force software onto users. It was definitely something i enjoyed about Gentoo (when i was using it), and also something i enjoy about Archlinux. ~ give your user-base a basic core system, and let them decide what they will or will not use / adopt.
Another reason distro's with build systems can be (more) pragmatic, is that we often can more easily get around license/legal issues (often) because we aren't actually shipping software with features enabled (that may not be redistributable, etc). And obviously ports/portage/ABS allow the user to modify things however they want to on their system.
I think OpenSuse should try sticking with tumbleweed and shift development in that direction. If they are concerned about breakage, than don't 'roll' as quickly as Gentoo or Archlinux... instead keep behind by a month or something. Then by the time you are ready to roll out new software, chances are (at least) any big ugly / over-looked bug(s) have probably been addressed/fixed.
Then OpenSuse users could kiss dist-upgrades and release-cycles goodbye ~ which is a good thing, IMO.... i wouldn't even consider using a distro that has 6month or even yearly releases. it's 2012 - we shouldn't have to re-install an OS every six months to a year, it's a bit of a joke, really.
I spoke too soon about Tumbleweed. I updated everything last night to linux 3.4.2 and KDE 4.8.4 and now right clicking any file in dolphin immediately crashes it. I filed a bug report and midnight commander works, but it's annoying. Hopefully it'll be fixed soon. I wouldn't mind waiting longer for updates if stability was better, but on the whole Tumbleweed has worked very well.
They were always set at a 9-month pace.
