However, I want to move forward with packaging SingularityCE 4.x for EPEL and there we need a newer squashfuse than is available in EPEL7.

This is so we can easily locate affected packages when e.g. a security issue necessitates fixing it. Also, since it wasn't clear from your text above: It's (generally) alright under these circumstances to bundle the extra packages, but you need to meet certain requirements: * The code that you're bundling still has to be built in Fedora. That probably means compiling it as part of your SingularityCE build. You may not ship code that was compiled somewhere else (e.g. upstream). * If you are shipping executables exclusively for use with your package, make sure they are properly namespaced in /usr/libexec/singularityce (or similar). This is to ensure that no other package accidentally tries to use your bundled version. -- _______________________________________________ epel-devel mailing list -- epel-devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to epel-devel-leave@xxxxxxxxxxxxxxxxxxxxxxx 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/epel-devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
