That's strange, I can also see this in my logs from back in April 2021,
but not since then.

As a shot in the dark, could you try the attached patch?  It's something
I added while looking at updating docker (I need to rebase this series
and get it committed). It's a bugfix, the patch-paths phase does not run
withouth it so it could be related to your issues. But for some strange
reason it's been working for me.

Subject: [PATCH] gnu: containerd: Fix patch-paths build phase.

* gnu/packages/docker.scm (containerd)[arguments]: Add 'patch-paths
phases after 'unpack because 'chdir doesn't exist.  Substitute runc
binary for "pkg/cri/config/config_unix.go".
