You curse aloud and use /dev/diskid/BLA-BLA-BLAp2 for swap because n= o > device nodes and no other labels are available and there is no way to > make them visible or create more human-friendly labels for partitions. But /dev/ada1p2 or /dev/ada0p2 will still be visible, so you can tell your system to swap there... Even better, if you use gpart labels, in which case you'll have a /dev/gpt/swap whoes name will remain constant irrespective of which of ada0 or ada1 the disk ends up as. This is the default setup created by the installer.
