[x] Just cp (save) to an old one, do not check if it contains anything. Assume it won't be good for us.
[x] At first, dl cacert.pem from curl site with curl --remote-name --time-cond cacert.pem https://curl.se/ca/cacert.pem.
[x] Extend option list with: --silent, --show-error, --location, --fail and --cacert cacert.pem (follow redirects and set a cacert, fail another way, be silent and show errors). cacert=cacert.pem
[x] Also use curlrc fix when installing xquartz and wine.
[x] Extra: switch HD and hot dl-s --silent to --progress-bar (UX :D ).
