Full Disk Encryption

[sullentrapdoor]

Hello! I was happy to see that lvm support was recently added to Guix 
System. This brings two questions.

The documentation is not clear on what LVM can even be used for at the 
moment. In the file `/gnu/tests/install.scm` from Guix, it mentions 
"guix currently doesn't allow root-on-LVM". I do not see a mention of 
this anywhere else in the documentation. I am not sure if this is true 
and if it, why it is true. Will support for "root-on-LVM" come soon?

If the above situation is possible, I would like to install Guix System 
with full disk encryption. Currently, I have two partitions on my disk, 
one the EFI and the other one a LUKS partition with LVM. On LVM I have a 
root, home, and swap partition. Is there any way at the moment that I 
can simply install Guix System to my root partition without modifying my 
luks/lvm setup?


Thank you!
