This swap file can be rejected by kernel on swap activation! Use --verbose for more details. mkswap: Label was truncated. I'm still green to know how to fix this, but I presume if I check out the latest version via git and the docs online, I should be able to update the definition for util-linux to include the patch, then try again?
