features:
  - The ``--mkfs-journal-size`` option is added to override the default
    journal size for basic ext4 root partitions.
Allow specification of filesystem journal size In many cases, the statically sized 64MB journal is far below the e2fstools default calculation[0] which calls for a 64MB journal only on filesystems smaller than 16GB. On bare metal in particular, the correct default journal size will often be in the 512MB-1GB range. Since we cannot know what the target system is, this should be a tunable parameter that the user can set depending on the intended image usage. Add a DIB_JOURNAL_SIZE envvar and --mkfs-journal-size parameter to the image creation so users can override the default journal size.
