freebsd/etc/rc.d/gbde
Simon L. B. Nielsen 64785dbd46 For the gbde attach script:
- Ask the user up to X times (3 by default) for the pass-phrase, if
  it is incorrect the first time.
- Add support for storing the lockfiles in another other directory
  than /etc.
- Document that it is possible to override the location of each single
  lockfile.
