does zram in fedora need any configuration

[Reindl Harald]

Hi

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the article below maybe outdated, on a rawhide-VM exists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?

[root at rawhide ~]# systemctl list-units | grep zram
sys-devices-virtual-block-zram0.device loaded active plugged /sys/devices/virtual/block/zram0
