- Fixed sfdisk PATH issue in Containerfile.base (sfdisk is in /usr/sbin)
- Updated Containerfile.minimal to use full path for grub-install
- Enhanced test-bootc-deployment.sh to properly check utility locations
- Added comprehensive section about related projects (apt-ostree, deb-bootupd, debian-bootc-corrected)
- Updated validation script to handle Debian-specific utility locations
- Improved error messages with specific solutions for PATH and utility issues
This addresses the critical requirements from scope.md regarding disk utilities
and PATH environment variables for bootc deployment.
