The Dockerfile.minimal (used for chroot mode) should also receive the same apt-get upgrade step for consistency. While chroot mode relies more on host binaries, the minimal image still includes iptables, iproute2, and git packages that could have security vulnerabilities. Consider adding the same upgrade step after the package installation in Dockerfile.minimal (after line 19).
