The shebang specifies bash, but Alpine Linux does not include bash by default and the script does not use any bash-specific features. Alpine uses ash (Almquist shell) by default. Consider changing this to #!/bin/sh for better compatibility with Alpine's default shell, or document that bash needs to be installed first. The other distribution scripts (Ubuntu, Debian, RHEL) correctly use #!/bin/bash because they use bash-specific features like source and bash parameter expansion.

Suggested change
#!/bin/bash
#!/bin/sh

Copilot uses AI. Check for mistakes.
