I have used aliases ... like never . IP-aliases are an obsolete way to manage multiple IP-addresses/masks per interface. Newer tools such as iproute2 support multiple address/prefixes per interface, but aliases are still supported for backwards compatibility. The "newer" iproute2 has been around two...

Your source code has static configuration. GLEW is a bad example, because it is already in the repo: $ sudo dnf --enablerepo=powertools list \*glew\* Last metadata expiration check: 0:00:17 ago on Mon 19 Apr 2021 04:49:04 PM EEST.

I have just done a reasonably large OS upgrade ...
