In some convenient timing, the following was posted by overtmind on<br>
Reddit discussing why Atom hasn't been packaged for Fedora(*):<br>
<br>
---<br>
"This means, for every nodejs dependency Electron needs - and there<br>
are a metric #$%# ton - since you can't use npm as an<br>
installer/package manager - you need to also package all of those and<br>
make sure they're in fedora and up-to-date, and then you also need to<br>
package all of the non-nodejs dependencies that come along with<br>
Electron apps, such as electron itself, and THEN you need to extract<br>
and remove all of the vendor'd libraries and binaries that essentially<br>
make Electron work, and THEN you need to make sure that there's no<br>
side-car'd non-free or questionable software that is forbidden in<br>
fedora also, like ffmpeg. G'head and look at the Chromium SPEC, it's a<br>
living nightmare (Spot godbless your heart)"<br>

Now obviously you could do what for example Java does with a jar file,<br>
and simply throw everything into a single rpm/deb and ignore the<br>
packaging guidelines, but then you are back to in essence creating a<br>
container and just hiding it behind a massive rpm/deb.<br>
<br>
>The thing we can never measure and thus can only speculate about forever<br>
>is: if all the person-hours poured into containers (and pypi/pip and cran<br>
>and cpan and maven and scons and ...) had been poured into rpm/deb<br>
>packaging would we just be simply apt/yum/dnf installing what we needed<br>
>today? (I'm ignoring other OS/packaging tools, but you get the idea.)<br>
<br>
I (theoretically) could write a new library in<br>
Python/Perl/Javascript/Go/etc. and with very minimal effort can place<br>
that library in the repository for that language with minimal effort.<br>
My library is now available to everyone using that language regardless<br>
of what OS they are using.<br>
<br>
Alternately, I could spend many, many hours perhaps even days learning<br>
multiple different packaging systems, joining multiple different<br>
mailing lists / bugzillas / build systems, so that I can make my<br>
library easily available to people on Windows, macOS, Fedora, RHEL,<br>
openSUSE, Debian, Ubuntu, ... - or alternately hope that someone will<br>
not only take the time to package my library for all those different<br>
platforms, but also commit the future time to keep it up to date.<br>
<br>
Option 2 worked 20 years ago when we only cared about 2 or 3<br>
distributions of Linux and had a lot less open source / free software.<br>
But, unfortunately, it does not scale and so for that reason (and a<br>
few others) the effort to create Docker / npm, maven, etc. is the<br>
lesser of the options.<br>
