The problem seem to be related to cow-store on VM produced by guix
system vm. I can reproduce it on "master" by running:

guix system vm /gnu/system/install.scm and appending -drive
format=raw,file=/home/mathieu/vm-test.img to the produced script.

Then,

mount /dev/sda1 /mnt
herd start cow-store /mnt

-> Every command (like ls ou mount) fails because /gnu/store does not
seem to be reachable anymore.

Is this a known issue, or am I missing something?

Thanks,

Mathieu
