This discussion revolves around the emerging trend of using bootable containers for Linux theming, allowing users to test and implement dotfiles and themes without altering their main system environment. Many users highlighted the efficiency of using containers for quick setups and experiments. However, there's a growing concern regarding the fragility of supply chains in these setups, particularly pertaining to various repositories used in packaging and the potential risk of vulnerabilities. Opinions varied, with some expressing a nostalgic appreciation for theming customization, while others pointed out the practicality of ZFS snapshots or NixOS for maintaining customizable environments. Overall, the conversation underlined the balance between the creative aspects of theming and the technical challenges posed by containerization, emphasizing the need for robust oversight in package management.
