+## Gotcha
+
+See <https://stackoverflow.com/questions/77969011/unable-to-add-certs-to-cacerts-with-eclipse-temurin-jdk-image>
+
+To avoid "unable to write file" during "make build".... this is how cacerts are installed using the script in `/__cacert_entrypoint.sh`:
+
+```bash
+#!/usr/bin/env sh
+# Converted to POSIX shell to avoid the need for bash in the image
+
+set -e
+
+# Opt-in is only activated if the environment variable is set
+if [ -n "$USE_SYSTEM_CA_CERTS" ]; then
+
+    # Copy certificates from /certificates to the system truststore, but only if the directory exists and is not empty.
+    # The reason why this is not part of the opt-in is because it leaves open the option to mount certificates at the
+    # system location, for whatever reason.
+    if [ -d /certificates ] && [ -n "$(ls -A /certificates 2>/dev/null)" ]; then
+        cp -a /certificates/* /usr/local/share/ca-certificates/
+    fi
+
+    CACERT="$JAVA_HOME/lib/security/cacerts"
+
+    # JDK8 puts its JRE in a subdirectory
+    if [ -f "$JAVA_HOME/jre/lib/security/cacerts" ]; then
+        CACERT="$JAVA_HOME/jre/lib/security/cacerts"
+    fi
+
+    # OpenJDK images used to create a hook for `update-ca-certificates`. Since we are using an entrypoint anyway, we
+    # might as well just generate the truststore and skip the hooks.
+    update-ca-certificates
+
+    trust extract --overwrite --format=java-cacerts --filter=ca-anchors --purpose=server-auth "$CACERT"
+fi
+
+exec "$@"
+
