Hi!
I've just added (service docker-service-type) to my list of services,
then run a `guix system reconfigure`, but dockerd fails to start.
/var/log/docker.log reports:
--8<---------------cut here---------------start------------->8---
time="2020-03-11T11:45:41.325992616+01:00" level=error msg="'overlay' not found as a supported filesystem on this host. Please ensure kernel is new enough and has overlay support loaded." storage-driver=overlay2
time="2020-03-11T11:45:41.326017293+01:00" level=error msg="[graphdriver] prior storage driver overlay2 failed: driver not supported"
--8<---------------cut here---------------end--------------->8---
Turns out that I needed
--8<---------------cut here---------------start------------->8---
sudo modprobe overlay
sudo herd restart dockerd
--8<---------------cut here---------------end--------------->8---
Can't Guix make sure the overlay module is loaded when the dockerd?
Related question: Can we configure Guix to load given modules on
startup? (Not in the initrd.)
Cheers!
