Version: 4.18.6-1~bpo9+1
Severity: important

Dear Maintainer,

I'm usign stretch + kernel from stretch-backports for to running nspawn containers. Containers are using plain debian stretch.
I've upgraded kernel from linux-image-4.17.0-0.bpo.3-amd64 to linux-image-4.18.0-0.bpo.1-amd64
I've seen next error with powerdns-recursor

I've investigate, that error appears caused by options PrivateDevices=true
I've create new container with debootstrap and test it with previous versions of the kernel
All kernels except linux-image-4.17.0-0.bpo.3-amd64 works fine.
