We get telemetry from Ubuntu, Fedora, and Arch (subject to choices made by the user). I'm not particularly worried about Debian, because x86_64 (as amd64) has had prominent (unlike Ubuntu; see below) availability from Debian pretty much for as long as x86_64 hardware has been available. But in any case, not enabling telemetry means not having representation in data-driven decision making. > At least current Ubuntu and Ubuntu LTS are still available in 32-bit: > https://www.ubuntu.com/download/alternative-downloads > > Ubuntu is our largest userbase (with telemetry...) The latest and the latest LTS are offered for 32-bit x86 only as netboot installers, and the latest LTS also as an upgrade from an earlier version, so Ubuntu now positions 32-bit x86 as more obscure than s390x, ppc64el, aarch64, and armv7hf. Ubuntu has already disabled automatic updates to 18.10 for 32-bit x86, because the expectation is that 18.04 will be the longest-supported release for 32-bit x86. I think the main problem with Ubuntu is that Ubuntu promoted 32-bit x86 downloads to users who didn't have the expertise to seek the x86_64 version for way longer than they, in my opinion, should have (though, in fairness, at that time, Mozilla also was promoting 32-bit x86 downloads over 64-bit). Users who installed Ubuntu at that time may have gotten a 32-bit distro even if the hardware would work just fine with the 64-bit version, and there are no upgrades from 32-bit to 64-bit other than reinstall. Probably more Canonical's job than ours to communicate to those users that they should do a 64-bit reinstall. (In terms of security support from the Ubuntu repos, I find the situation for architectures that aren't tier-1 for us a bit concerning. Compare https://packages.ubuntu.com/search?suite=disco&searchon=names&keywords=firefox with https://packages.ubuntu.com/search?suite=cosmic&searchon=names&keywords=firefox . Despite 32-bit x86 having been demoted below s390x, ppc64el, aarch64, and armv7hf in terms of distribution images, 32-bit x86 gets better security support in the Ubuntu repos than s390x, ppc64el, aarch64, and armv7hf. So does security support in Ubuntu repos depend on our tier positioning or to Ubuntu's own positioning?) -- Henri Sivonen hsivo...@mozilla.com _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
