I implemented a different logic now:
With this change we'll now dispatch only one mkswap per device node,
regardless which symlinked alias is used to refer to it. I have only
given this very light testing, and I am not sure this solves the
original problem you reported, hence I'd be thankful if you could
check if this makes the problem go away.
