Workaround that enables further testing (disables selinux on boot): #cloud-config: bootcmd: - setenforce 0 packages: - tmux - firewalld - vim - nginx - wget runcmd: - [systemctl, enable, nginx.service] - [systemctl, enable, firewalld.service] - [wget, "http://roshi.fedorapeople.org", -O, /tmp/index.html] - [firewall-cmd, --add-service, http] - [cp, /tmp/index.html, /usr/share/nginx/html/] Added workarounds to the CommonBugs page. Adding the CommonBugs URL. RPM insists on running scriplets with system_r:rpm_script_t role and tyoe. The policy has to facilitate that. I never understood why the scriptlets have to fail in enforcing mode if they are not run with system_r:rpm_script_t. Nor do i understand why this is hard-coded into RPM. (In reply to dac.override from comment #4) > RPM insists on running scriplets with system_r:rpm_script_t role and tyoe. > The policy has to facilitate that. > Can we get the policy to facilitate this transition? Is anyone looking to make this happen? commit 257ed1a2706ce8ae6d1f54f6c311c3e50d44c768

BZ(1227484) When will this get built?

Description of problem: Feel free to re-assign this bug to the appropriate component as I don't know what that is right now. Basically if I try to install packages using cloud-init in the Fedora 22 cloud image then I get denials and my install scriptlets don't work: type=AVC msg=audit(1433271374.623:169): avc: denied { transition } for pid=872 comm="dnf" path="/usr/sbin/ldconfig" dev="vda1" ino=4512 scontext=system_u:system_r:cloud_init_t:s0 tcontext=system_u:system_r:rpm_script_t:s0 tclass=process permissive=0 type=AVC msg=audit(1433271375.095:170): avc: denied { transition } for pid=873 comm="dnf" path="/usr/bin/bash" dev="vda1" ino=4844 scontext=system_u:system_r:cloud_init_t:s0 tcontext=system_u:system_r:rpm_script_t:s0 tclass=process permissive=0 Version-Release number of selected component (if applicable): Fedora-Cloud-Base-22-20150521.x86_64.qcow2 How reproducible: Always Steps to Reproduce: 1. Start cloud image with the following user-data and observe errors in audit.log and journalctl output during boot: #cloud-config: packages: - tmux - firewalld - vim - nginx - wget runcmd: - [systemctl, enable, nginx.service] - [systemctl, enable, firewalld.service] - [wget, "http://roshi.fedorapeople.org", -O, /tmp/index.html] - [firewall-cmd, --add--service, http] - [cp, /tmp/index.html, /usr/share/nginx/html/]
