Comment # 3 on bug 904987 from Federico Vecchiarelli

I found a mention of this problem in this thread:

https://www.mail-archive.com/initramfs@vger.kernel.org/msg03622.html

The actual thread mentions a few things but you will find the same particular
issue happened. Here is an excerpt:

Note that I don't have an entry for this luks device in /etc/crypttab. I
always thought that this is not necessary since all needed options
are in cmdline.

If the best is to write a wiki article about it, I surely can give that a try.
