[Bug 1810235] Re: cryptsetup silently fails in live environment

[Andreas Hasenack]

Could this be solved with different ordering? Luks first, then bcache?
Luks definitely expects its header to be in a certain position:

LUKS EXTENSION
       LUKS, the Linux Unified Key Setup, is a standard for disk encryption.  It adds a standardized header at the start of the device, a key-slot area directly behind the header and the bulk data area behind  that.  The
       whole  set is called a 'LUKS container'.  The device that a LUKS container resides on is called a 'LUKS device'.  For most purposes, both terms can be used interchangeably. But note that when the LUKS header is at
       a nonzero offset in a device, then the device is not a LUKS device anymore, but has a LUKS container stored in it at an offset.
