I have a similar problem. I worked around the selinux issue here by just temporarily setting it to permissive, but that's not enough. The netlify/build:focal image sets several files in buildbot's home directory to owned by root:root.

As Podman runs unprivileged by default, it trips on these files, especially the package-lock.json and /opt/buildhome/repo directories.

$ ls -lah /opt/buildhome/
