in case of cloud / virtualization i wonder what is the

zram IMHO would be interesting for the guest systems and
both combined may lead to run *a lot* of more virtual
machines on the same host

I enabled zram in rawhide at the end of January. It was done for bug
1058072 because zram finally moved out of staging with the upcoming
3.14 kernel release.
Fedora release branches will get this enabled when they rebase to 3.14.
