Qubes that have the updates-proxy-service enabled will have the
repository definitions set to work with the proxy, being it a TemplateVM
or another type of qube. Qubes that have that same service disabled and
are based on templates that are being cached, will have the repository
definitions corrected for it to work like normal systems via the
networking instead of caching proxy.
Optimizations were done for a faster runtime, previously it would call
sed 38 times on Fedora-39, now it only calls sed 2 times for Fedora
repositories (one extra for rpmfusion) and some more for PackageKit and
dnf.conf markers. Inexpensive runtime is a must for a script that may
run multiple times, such as when being called by a tool monitoring the
filesystem such as inotify.
Code from /usr/lib/qubes/update-proxy-configs was used for the NetVM use
case of the cacher, thus the license had to be changed.
