What's missing is support in the configuration system: the ability to
declare a LVM mapped device in the OS configuration and expect 'guix
system init', 'guix system reconfigure' etc to work.

LVM 2.03 simplifies things a bit, but I don't know of any recent
attempts to add LVM support to the configuration system.
