[Nix-dev] systemd failed in locating swap

[Dmitry Malikov]

Hi.

Trying to `nixos-rebuild switch` and got something strange.

A dependency job for swap.target failed. See 'journalctl -xn' for details.
warning: the following units failed:

warning: error(s) occured while switching to the new configuration

Related attributes from a nix-repl:
nix-repl> :p config.swapDevices
[ { device = "/dev/sda2"; encrypted = { blkDev = null; enable = false; 
keyFile = null; label = null; }; label = «error: The option 
`swapDevices.[1-1].label' is used but not defined.»; priority = null; 
size = null
; } ]

I'm not quite sure what is going on here, but hardware-configuration.nix 
looks fine for me and nothing was really changed.
