Restructure the ATVM folder to separate executable scripts from workflow documentation and long-form environment reference material. Move setup and automation scripts into scripts/, move setup and automation guides into docs/, add top-level README and workflow conventions, and organize durable environment details into inventory/ while preserving the original long-form ATVM notes under archive/imported-notes/. Update internal documentation paths to match the new layout and remove the archived Zone.Identifier metadata file.

# ATVM VM Setup Script
|
|
# Combined script that:
|
|
# 0. Validates target host identity using expected IP + hostname
|
|
# 1. Fixes repository configuration (removes DVD/CD-ROM entries)
|
|
# 2. Configures Ubuntu root SSH/password workflow
|
|
# 3. Sets Oracle Linux default kernel to non-UEK
|
|
# 4. Disables Ubuntu unattended auto-upgrades
|
|
# 5. Installs cross-distro packages
|
|
# 6. Disables SELinux (Red Hat-based systems only)
|
|
# 7. Configures Static IP as the final step (All distributions)
|
|
# 8. Reboots SELinux-capable distros and verifies SELinux after boot
|
|
# 9. Keeps client powered on until controller-side log copy + hash verification complete
|
|
# 10. Requires controller-side power-off only after successful verification
