Bug Description
With the rise of newer filesystems, there are devices which may not actually contain a filesystem, but are used, i.e. as a caching device.
Case in point; I have a HDD and a SSD (a combination which is getting more and more common). My HDD contains a ZFS filesystem, the SSD is used as a "cache".
The same holds true for systems such as bcache.
However, to be safe, one may wish to encrypt these filesystems. Encrypting the cache is then also a good thing, as the cache may contain data equally sensitive.
However, when using a LUKS encrypted volume, the initramfs "cryptsetup" (in local-top) script checks the output from blkid, and errors out if the the device cannot be found in blkid.
I propose an extra option passed via /etc/initramfs-
