mailing-list stripped the 3.9 KB src.rpm :-( http://access.thelounge.net/harry/zram-1.0.0-1.fc20.20140327.rh.src.rpm

answered that myself

• it needs configuration
• src.rpm built on F20 and tested on Rawhide attached
• that below is a VM with 2 virtual CPU cores
• configuration is 20% of RAM and one zram-device per core

...

since 3.14 is not that far away zram becomes interesting

the article below maybe outdated, on a rawhide-VM exists /dev/zram0 as well as a implicit systemd-unit, well does that mean it is automagically configured and if that is the case does systemd < 212 that also or is there handwork needed for the time F19/F20 get rebased to kernel 3.14?
