Swap partition does not mount with Arch install on btrfs

view story

https://bbs.archlinux.org – I have my Arch install on a btrfs partition (sda1) with one swap partition to go with it (sda2). I used "swapon" on my first install and set up the fstab for swap but every time I boot systemd warns me that it cannot mount the swap partition because of a "dependency" problem.  I understand that we are not supposed to use swap FILES with btrfs, but I was under the impression that swap PARTITIONS should work. Is there any way to get my swap partition up and running? Failing that, should I just edit my fstab to get rid of the swap entry so I don't get the annoying er (HowTos)
