bug#56209: Shepherd 0.9 not cleanly unmounting root

[angry rectangle]

Since the upgrade to shepherd 0.9, I get "recovering journal" every single time 
I start my computer.
To be specific, "recovering journal" appears after I enter my encryption 
password in the initrd.
I assume this means the filesystem wasn't cleanly unmounted.
I am doing a proper shutdown, using either "reboot" or "halt." 

I've attached the minimal config I've been using.
It's nothing special other than encrypted root.
I'm using an SSD with a gpt partition table.
No custom packages or external channels were used when configuring the system.

This is for my desktop computer, but I have the exact same problem with a 
similar minimal config on my laptop.
Mostly the same sitution there with an SSD, gpt table, and encrypted root.

The guix commit 400c9ed3d779308e56038305d40cd93acb496180 is the specific commit 
that upgrades shepherd and causes me this problem. The previous commit is fine.
I'm can confirm that it's still broken on recent commits. I'm on 
696e2cc345f015c32f211bf0d0330c04b1cf5f15.

Thanks
