+# Lessons Learned
+
+## Fedora Kickstart
+
+### Network
+
+The installer was able to retrieve Kickstart files via HTTPS through Pangolin.
+
+### DNS
+
+Initial tests indicated DNS resolution issues. Verification showed that network connectivity was available and the Kickstart file could be downloaded.
+
+### Disk Naming
+
+The virtual machine used:
+
+* VirtIO SCSI controller
+* SCSI disk (scsi0)
+
+The installer exposed the disk as:
+
+/dev/sda
+
+not:
+
+/dev/vda
+
+Therefore:
+
+ignoredisk --only-use=vda
+
+caused installation failure.
+
+### User Accounts
+
+An unattended installation requires either:
+
+* a valid root account configuration
+* or a local user definition
+
+### Post Installation
+
+The following actions were successfully executed in %post:
+
+* MOTD creation
+* Git installation
+* Ansible installation
+* Repository cloning
+
+### Architectural Validation
+
+The following concept has been successfully validated:
+
+Generic installation media
+→ Activation service
+→ Profile
+→ Installer definition
+→ Automatic installation
+→ Git repositories
+→ Configuration management
+
