This can cause the build to hang forever. Go language does not support sparse files correctly, which can lead to some huge files being created in your container image. If you are using `useradd` within your build script, you should pass the `--no-log-init or -l` option to the `useradd` command. This option tells useradd to stop creating the lastlog file. |
