I.e., I usually don't exactly have opinions, but questions based on, "Okay, if we're going to do X, why not Y or Z?" I mean, if we're going to look at dropping one (e.g., BTW/bzip2), then why not just remove it altogether? Or at least reduce the value and questions to awareness only. (perhaps NIST does, but we here in Europe don't care that much about NIST). > I was just pointing out that some (e.g., LZ4/p7z) have program that are getting blacklisted by the US, which does affect some American allies as well, and definitely American companies operating in Europe (and elsewhere).

I think LPIC-1 will eventually be unable to avoid the awareness level at some point.** - bjs **P.S. We're at the point in my current environment where we're pushing out Containers to run under WSL2, including using Ansible playbooks to configure/manage them. But WSL2 isn't on the exam, of course. -- Bryan J Smith - http://www.linkedin.com/in/bjsmith E-mail: b.j.smith at ieee.org or me at bjsmith.me
