Actual behavior
error creating overlay mount to /var/lib/docker/overlay2/af8c5d19cde2039cf3b4c3b340b960bac2b2f0504b0b291f6c63c2d5175ea3ba/merged: device or resource busy
dmesg:
[55383.848708] overlayfs: lowerdir is in-use as upperdir/workdir
( https://gitlab.com/freedesktop-sdk/infrastructure/freedesktop-sdk-docker-images/-/jobs/242656806 )
Steps to reproduce the behavior
Install Fedora 30 and update the kernel to 5.1.15-300.fc30 (latest at time of creation of this issue)
Then as root:
git clone https://gitlab.com/freedesktop-sdk/infrastructure/freedesktop-sdk-docker-images.git
cd freedesktop-sdk-docker-images
docker build .
# Then docker push somewhere...
Note: kernels that do not have this commit do not suffer from the issue. It looks like this commit added more sanity checks around usage of overlayfs and docker is using overlayfs wrong. I could work around the issue by using an older kernel.
