Revision 29aef439

Added by Jim Pingle over 5 years ago

RAM Disk robustness improvements. Fixes NG 3173

  • Prevents RAM disk from being partially enabled and left in a broken
    state if the RAM disks cannot be created
  • Prevents RAM disks from potentially overcommitting free kernel memory,
    which FreeBSD now prevents, but could result in errors.
  • Adds GUI input validation to prevent exceeding free kernel memory when
    sizing RAM disks
  • Ensures the pkg database is always available whether setup for disk
    storage, RAM disks, or if set for RAM disks but they failed to work
  • Moves RAM disk script functions to a common file for reuse.
  • Files a notice to alert the user that RAM disks failed and to check
    the disk sizes
  • Generally makes the RAM disk setup process more verbose on the
    console. These messages can be commented out or removed in the future,
    but are helpful for the time being.
