It would appear that cfs is not compiled in the Raspbian Kernel. :(

[honomoa]

I am using docker-ce_18.09.0~3-0~debian-buster_armhf.deb and it works.
But it not works on docker-ce_18.09.9~3-0~debian-buster_armhf.deb

Not sure if it works or not after update raspbian kernel by sudo rpi-update

[baimard]

It would appear that cfs is not compiled in the Raspbian Kernel. :(

Would we have to open a ticket in raspbian project ?

[bullimog]

You could open a ticket, but (guessing) I think cfs is disabled intentionally, to maximise performance for regular end user applications.

I am looking at using hypriot to get Docker on RPI, instead.
