Not sure what is in Koji, so just some facts about the Copr arm builders... Copr uses 'a1.2xlarge' machines: https://aws.amazon.com/ec2/instance-types/a1/ Copr uses mock's tmpfs feature, with cca 140GB SWAP volume on a gp2 disk: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/general-purpose.html Pavel > -- > 真実はいつも一つ！/ Always, there's only one truth! > > _______________________________________________ buildsys mailing list -- [email protected] To unsubscribe send an email to [email protected] Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/[email protected] Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
