Does that address your concerns?
Alternatives to EPEL
Q: Are there alternatives to using the EPEL repository?
A: Depending on your needs‚ shouldn’t you explore other options before relying solely on EPEL? If you need a specific package‚ have you checked if it’s available as a container image (e.g.‚ Docker‚ Podman)? Wouldn’t that provide a more isolated and potentially more secure environment? Or could compiling directly from source be an option‚ albeit with more manual effort?
Q: What about using Software Collections (SCLs)?
A: Have you considered Software Collections as a way to access newer versions of software without affecting the base system libraries? Wouldn’t this provide a more controlled environment for running specific applications that require newer dependencies? Isn’t this a better option than potentially disrupting the stability of the entire operating system?
Q: What are the risks of relying too heavily on external repositories?
A: Aren’t you aware that relying heavily on external repositories like EPEL can introduce dependencies and complexities that might make your system harder to manage and troubleshoot? Shouldn’t you strive for a balance between convenience and long-term maintainability? Have you considered the potential impact on system stability and security when incorporating external software sources?
