What is the current behavior (link to any open issues here)?

Some files and directories were not readable by the image user. Doing ls would fail:

$ podman run --rm --entrypoint=bash localhost/postgres-operator -c 'shopt -s globstar && ls -ldh /licenses/** /opt/crunchy/**'

ls: cannot access '/licenses/cel.dev/expr@v0.24.0': Permission denied
ls: cannot access '/licenses/github.com/antlr4-go': Permission denied
…
ls: cannot access '/opt/crunchy/conf/pg11/queries_general.yml': Permission denied
ls: cannot access '/opt/crunchy/conf/pg11/queries_pg_stat_statements.yml': Permission denied

What is the new behavior (if this is a feature change)?

No errors from ls. The same command above returns:

second build was much faster with this

[benjaminjb]

Do we want to use a different image (following today's discussion)

[cbandy]

Meh. It can wait.
