Environment-portable configuration management

Ensure all configurations are environment-portable and follow current best practices for the target platforms. This includes:

1. Using environment variables instead of hardcoded paths or user-specific values
2. Keeping base images and dependencies updated to supported versions
3. Adapting installation methods to platform-specific best practices
4. Verifying package availability across target environments

Examples:

Instead of:

rm -rf /Users/username/vtdataroot/*

Use:

rm -rf "${VTDATAROOT:-./vtdataroot}"/*

For Docker configurations, regularly review base images:

# Review regularly to keep updated
FROM --platform=linux/amd64 golang:1.23.4-bookworm

# Research platform-specific installation methods
RUN echo "deb http://repo.mysql.com/apt/debian/ bookworm mysql-8.4-lts" > /etc/apt/sources.list.d/mysql.list

When packages change across OS versions, document and adapt:

# For bookworm, use these packages instead of the deprecated 'etcd'
apt-get install -y etcd-client etcd-server
