I will soon have the opportunity to reinstall netbsd 1.2
  on a fresh drive, while still having my older drive.
  I saw mention on this list that the Installer and Mac mkfs
  utilities know how to create 4.2/4.3 FFS filesystems,
  while the unix mkfs can do 4.4 FFS filesystems. I
  have no idea what the difference is (is the FFS on-disk
  layout still changing?)

  Can someone explain the benefits/drawbacks of the 4.4 variant
  on FFS? If I make the filesystem from the unix side will
  I still be able to use the Installer minishell to cpin and
  cpout? Are there any other caveats?
