So Fedora 24 Alpha is out for aarch64 and POWER . Keen followers will note that we were a couple of days behind the primary architecture’s Alpha release, which hasn’t been the case for the last few Fedora cycles where we’ve generally released on the same day.
The primary reason for the delay was the Pungi Refactor . While the pungi 4 change has been massive for primary architectures for the secondary architectures it’s the single biggest change to our release process EVER! Basically we’ve thrown the lot out and started again. When I started in release engineering over 18 months ago the number one goal that was set for me can be summarised as “Be more like primary. Make the whole secondary architecture as close to primary as possible!” and we’ve been continuously moving, albeit not as fast as I would have liked, in that general direction. With the arrival of pungi 4 for Fedora 24 we’re almost at that end goal in terms of the current way we do secondary architectures.
With Fedora 24 we’re also adding a lot more release engineering focused features and functionality to the secondary architectures. We have now have full nightly composes on rawhide and branched whereas previously we’d just produce a “Everything” repo. This allows ongoing continual testing on things so it’s easier to know when things regress. On PowerPC we’ve produced qcow2 cloud images to some degree since Fedora 22 but it was a bit of a manual process. These are now fully integrated into the pungi/koji process and, like on primary produced nightly, similarly they’ll be coming to aarch64 very shortly too. In Fedora 24 we’ve added Docker base images, they’re produced nighly on branched and rawhide for PowerPC now, and will be nightly for aarch64 at the same time the qcow2 cloud images arrive. Finally aarch64 will also soon have disk images like ARMv7 on primary to enable us to easily support the new shiny aarch64 Single Board Computers (SBCs) that are _FINALLY_ becoming available for the architecture, for Fedora 24 it’ll be a bit of a hack, but with Fedora 25 both ARMv7 and aarch64 will be able to move to koji based live-media-creator image build process but I’ll outline more of that in another post.
So the pungi refactor has been big for the secondary architectures. It’s required big changes in our infrastructure which is now mostly complete, there’s a few infrastructure cleanups and final changes that are in process, these will be done in the next few weeks in the lead up to Beta. We have a single host left to migrate to ansible (YAY!!) and some final moving around of resources. We’ll be changing the way we sync content out to mirrors too which will close out one of the final deltas of the rel-eng secondary process. Overall the last few weeks have been challenging getting all the bits in place, but by the time we hit Beta it’ll all be complete! The new processes lay the foundations for the secondary architectures to add functionality quicker than ever before, and by being almost identical to primary the “onboarding” of new people to use that process, or end users be able to consume the output of the rel-eng process is easier than ever before and that makes me happy!
