To find this out is part science and part guesswork. Starting with: https://github.com/openstack/requirements#finding-distro-status I get the following: Xenial: [ 8.25 ] https://packages.ubuntu.com/search?keywords=coreutils&searchon=names&suite=xenial-updates§ion=all Fedora: [ 8.27 ] https://apps.fedoraproject.org/packages/coreutils Gentoo: [ 8.27 ] https://packages.gentoo.org/packages/sys-apps/coreutils RHEL7 - Centos 7: [ 8.22 ] http://mirror.centos.org/centos/7/os/x86_64/Packages/coreutils-8.22-18.el7.x86_64.rpm opensuse: [ No idea ] https://build.opensuse.org/package/show/Base:System/coreutils But pages like: https://www.suse.com/support/update/announcement/2013/suse-ru-20130546-1.html imply that 8.12 is still a thing in SLES-11 So while we support SLES 11 I don't think we can make that assumption. Which of course begs the follow-up question which distros do we care about. Yours Tony. -------------- next part -------------- A non-text attachment was scrubbed...
