From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If I'd decide to implement something like this, I'd consider two options: local repo with
file://
scheme or custom apt-transport. HTTP server is needless here. (But I'll never do this because I prefer to rebuild packages myself if there's no repo for my distro.)With that, I couldn't trigger a download when
apt update
is ran, I could only do a cron, i.e. a delay, that I do not want.I thought about that, but found no documentation on how to do it. If you have any, I'm interested.
Even just finding documentation on how to generate DEBs and APT repository metadata files was very hard.
differently hacky idea:
since you do end up with all the packages in a repository on the filesystem, and you just want to have it do this just-in-time updating when the Packages file is accessed...
what if you list it as a normal
file
apt source, but you make the Packages file a FIFO?it's a cursed idea but I'm not sure it is any less cursed than the other options we've come up with.
it may or may not help to have systemd.socket manage creating the FIFO and running the service.
What's a FIFO ?
I've also looked into VFS but found nothing I'd have the skills to implement. 😅
