ok to the naming and multi zram devices questions:

1) one single large space is wasteful if you have your machine up for longer than a  single (or series ) of heavy lifting operations  --say you are rendering a video and then back to the usual grind stuff would you want all that extra space just wasted ?  also say a follow up process is in need of more would you wanna be stuck on previous values?   zram is dynamic in nature smaller more numerous /dev/zram$i  allows for that and in a dynamic manner...

2) it the RAM its based off not swap and the "z" is known as dynamic

Reindl, I'm of the opinion you should upload your scripts to some git
repository and package them to be part of the distribution. I can
co-maintain if you wish

feel free to package it!

that's why i attached it as i saw the topic
i am not a active packager on the Fedora infrastrcuture

Ok, I've uploaded the scripts to GitHub and submitted a review request:

I have a question about the code: why are multiple swap devices needed?
/sys/block/zram0/max_comp_streams can be set to whatever number is
wanted. While it might be useful to have additional zram devices
for different purposes, I don't think more than one zram swap is
useful. If you only have one device, then reloading the module is
no longer necessary to change the parameters, since everything
else seems to be configurable through sysfs.
And another question (sorry, I never used compressed swap before):
why not zswap? It seems to be a better fit for the desktop/server
environments that Fedora is used for. IIUC, zswap is better because
it overflows automatically into the backing swap device

on machines with plenty RAM i prefer not have a swap partition or a swap file at all - especially on virtual machines it's a waste of (possible expensive SAN) disk storage

on virtual servers currently i prefer zram inside the guest to avoid OOM conditions in the guest while the memory compression of the hypervisor steps in too late and is more for overcommit the host
