gets swap really still actived twice by systemd?
There is a section about systemd trying to activate swap twice, and several ideas how to work around the error message which appears due to the second attmept to swapon. Is it still an issue? I think Lennart fixed this maybe: https://lists.freedesktop.org/archives/systemd-devel/2015-January/027521.html and the following mails... Mearon (talk) 05:45, 22 November 2016 (UTC)

- I've tested it on the lastest Arch install from the April ISO and can confirm that the issue is fixed. Also I think there should be a clarification regarding the fact that systemd only looks at the disk containing the root filesystem. So if you have swap on a separate disk systemd fails to autoload it without an fstab entry. Should I remove the section and add the clarification above. Hashhar (talk)
Can we add more documentation on what this is? How it works? What's the difference between Swap File Universal and Swap File Chunked? Do we need to activate both zram and zswap? Do we need both swapfu and swapfc? When would we want a certain configuration? Where is the swap file located? Can we use this to enable hibernation?
- That information seriously belongs to https://github.com/Nefelim4ag/systemd-swap -- not here, since they are just details for the script. We already describe the background info in Swap, Zswap, Improving_performance#Zram_or_zswap and Power_management/Suspend_and_hibernate#Hibernation, your questions can be answered by simply reading the script. -- Lahwaacz (talk) 16:59, 11 January 2017 (UTC)
