Description

Entering a fakeroot inside a container used to be instant but now takes about a minute.

Reproduce

docker run -it --rm alpine
apk add fakeroot
fakeroot

Expected behavior

The original behaviour - fakeroot being quick.

Additional Info

Can also be reproduced on Fedora. Can't be reproduced with podman which is why I suspect a docker regression rather than a fakeroot one.
