Bug 1806527

STEP 10: RUN rpm-file-permissions &&   useradd -u 1001 -r -g 0 -d ${HOME} -s /sbin/nologin       -c "Default Application User" default &&   chown -R 1001:0 ${APP_ROOT}
useradd: /etc/passwd.355: lock file already used
useradd: cannot lock /etc/passwd; try again later.

It works fine if i manually clone https://github.com/sclorg/s2i-base-container.git, cd into 'core' directory, and run:

buildah bud --tls-verify=false --no-cache -f Dockerfile.rhel8 -t image-registry.openshift-image-registry.svc:5000/custom-images/s2i-custom-core:latest .

Here is my ClusterTask for buildah:
