Non-Existent Cron Directory Causing Auto-Backup to Not Trigger

[algo7]

When the setup_cron fuction is called in the entrypoint.sh in the docker container, it does not check for the existence of the directory$HOME/cron.d.

I am using image version: mbround18/valheim:2.4 and it seems like the /home/steam/cron.d is not created as part of the Docker image build nor as part of the entrypoint.sh. The missing directory has caused the cron job setup to fail as can be seen from the server log attached below. For me, the auto-backup is not working for this reason. I assume that other jobs such as auto-update and scheduled restart that depend on cron will also fail to work. It seems like the problem also exists in previous version of the image, because my backup stopped long ago and i have updated my image several times throughout the past few months. I have not realized this until I updated my image to 2.4.

Is it possible to issue a fix by either creating the directory during the image builds or as part of the entrypoint.sh?

setup_cron function in entrypoint.sh

setup_cron() {
  set -f
  CRON_NAME=$1
  SCRIPT_PATH="$HOME/scripts/$2"
  CRON_SCHEDULE=$3
  LOG_LOCATION="$HOME/valheim/logs/$CRON_NAME.out"
  mkdir -p "$HOME/valheim/logs"
  [ -f "$LOG_LOCATION" ] && rm "$LOG_LOCATION"
  printf "%s %s /bin/bash %s >> %s 2>&1" \
    "${CRON_SCHEDULE}" \
    "BASH_ENV=/env.sh" \
    "${SCRIPT_PATH}" \
    "${LOG_LOCATION}" \
    | tee "$HOME/cron.d/${CRON_NAME}"
  echo "" | tee -a "$HOME/cron.d/${CRON_NAME}"
  # Give execution rights on the cron job
  chmod 0644 "$HOME/cron.d/${CRON_NAME}"
  set +f
}
