So... if you want to learn how to write and submit packages to 
Guix -- please do!  And don't let me distract you.  Your patch 
looks good, if incomplete :-)

However, if you need/want a working Guix bcache-tools package 
ASAP, I have to admit I've been sitting on the attached patch for 
so long I that forgot it wasn't upstream yet.

Sounds useful.  What does this patch do?  Is it related to Guix 
(perhaps our blkid)?

I think The GNU Way is ‘user space’, ‘file system’, ‘write-back’ 
etc.  Be sure to double-space prose sentences; ‘guix lint 
bcache-tools’ will warn you about this and other possible surface 
issues.

This description sounds out of date (it's been upstream since the 
3.x days) and the ZFS comparison is presumably meaningful only to 
a small minority of ZSF-on-Linux-Libre users.  IMO try to describe 
packages in first-class terms so users don't get sent on a rabbit 
chase.

Feel free to snarf my description but don't feel obligated either.

Kind regards,
