What is the difference between physical swap and having a swap partition on ZRAM, especially for the kernel? To the best of my knowledge, nearly no Linux distribution supports suspend to disk any more, any ZRAM swap looks for the kernel like … swap. Thanks to the virtual file system. Further, I have high trust in the Fedora community, which decided to use ZRAM.
We can agree to disagree about the firewalls, especially for people who don’t now why their stuff isn’t working, it protects them and is much better than having unconfigured services with open ports on a laptop in a public network IMHO.
