VM-based end-to-end test using Fedora cloud image with two disks:
root (20GB) + data (200GB). Verifies the firstboot script creates
labvg with correct LV sizes, mounts volumes, migrates /home content,
sets hostname, creates admin user, and handles reprovision.
Fixes to firstboot script:
- Detect whole disks (not just partitions) for LVM PV
- Handle btrfs subvolume paths in root device detection
- Copy /home content before mounting LV (preserves SSH keys)
- Don't restart sshd (config takes effect on reboot)
- Make swapon and mount operations resilient to failures
