New Revision: 293115
URL: https://svnweb.freebsd.org/changeset/base/293115

Log:
  Use /bin/rm to remove /firstboot*. Otherwise rm -i alias is picked
  up and can cause issues on boot with the prompts. Fix the read-only
  root case with horrible kludge of mounting rw removing the files, then
  mounting ro. But since that's no more horrible than the kludge of
  using marker files in /. With this change, NanoBSD configs can safely
  use /firstboot + growfs to produce minimal images that grow to the
  size of the card.
