As Xose suggests it is likely related to the new systemd hardening restrictions which are applied for httpd from Fedora 40. There is a bit more information in "man httpd.service." Exactly what directory are you trying to write to? /usr is blocked by ProtectSystem=yes, /home is blocked by ProtectHome=yes, for example. Writing to /tmp works fine OOTB for a trivial CGI in /var/www/cgi-bin for me - if that is failing you please file a bug. (Because PrivateTmp has been used for a *long* time in httpd, httpd's /tmp is different to the system /tmp) Regards, Joe -- _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to 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/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
