Congratulations to the Ubuntu team, on a successful gutsy release. While gutsy is currently a little buggy for me, the millions of eyes will hopefully find all the bugs responsible… (and I must get around to filing the relevant launchpad bugs)

I run a teeny weeny little mirror (by International standards, for South Africa, it’s OK), so I’ve followed the release process, and been hanging out on #ubuntu-mirrors since last night. Preparing an Ubuntu release is quite an undertaking. In total, each mirror needs to carry around 20-30 CD images, and 4 DVD images. That’s reasonable chunk of data, and it takes a lot of coordination for everybody to get it.

I see many distros release, we normally pick them up automatically, and notice their presence the next day. But there’s definitely something special about Ubuntu releases. They have the feel of a release. The tension builds up the night before, and the #ubuntu-release-party channel fills up (when I popped in, around 500 people). Then, a few hours before the release is announced, people start noticing that it’s on the mirrors. Pointing this out on the release-party channel is not allowed (it would disturb the otherwise rowdy party of 500 users pressing F5 every 10 seconds), but pretty quickly, before the release is even announced, all the mirrors that carry Ubuntu CDs get flat-lined. If they don’t, then it’s a sign that their hardware isn’t up to scratch, and they have to find & fix their bottlenecks. On the #ubuntu-mirrors channel, you can see sysadmins from around the world showing off graphs of flat-lined, multi-gigabit links and sharing server tuning tips. If you want any experience in widely-distributing large files, run an ubuntu mirror at release-time, you’ll gain the experience fast.

I don’t know if this massive assault means Ubuntu is the most popular distribution out there. Most Ubuntu users don’t need the new ISO. They rather need click the big “upgrade” button, and hammer their local mirror to the tune of about a gigabyte. Ubuntu is based on Debian’s awesome package management system, that (if used correctly) should never require a re-install. There are Debian systems out there that were installed once, back in the 90s, and have been upgraded (both distro versions and hardware) continuously since then. Do people not know that, or do they want the thrill of booting up with the new Gutsy CD? Debian is widely considered to be the most popular distribution, and a Debian release hardly raises eyebrows (other than somebody saying “Debian released? Has hell frozen over?”, and scheduling an upgrade for some time in the next 6 months). If nothing else, this shows how different distributions’ user-base can be, while being technically very similar.

I’ve done my bit to help out the Ubuntu release:

• I’ve been running Gutsy since it’s fork, and filed god only knows how many bugs on launchpad.
• I’ve created my unofficial package DVDs, for people without Internet connections.
• My mirror & toaster had the CD images in advance, and we’ll have the DVDs by tomorrow morning.
• I’ve got a UK server with a 100Mbps link seeding Ubuntu DVD torrents. I was the sole seed for many hours, and have uploaded over 200GB, so at least I did some good ;-)

Now, as the release traffic dies down again (i.e. heavy but not quite flat-lining), I hope the sysadmins and release-party-goers sleep well, you all deserve it.
