I can co-maintain if you wishfeel free to package it! that's why i attached it as i saw the topic i am not a active packager on the Fedora infrastrcutureOk, I've uploaded the scripts to GitHub and submitted a review request: https://github.com/jorti/zram-swap https://bugzilla.redhat.com/show_bug.cgi?id=1168692I 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
