#
# NOTE: Tripwire creates temp file in its current working directory.
# This policy does not allow write access to home directories, so
# users will need to either cd to a directory where they have write
# permission, or set the TEMPDIRECTORY variable in the tripwire config
# file. The latter is preferable, as then the file_type_auto_trans
# rules will kick in and label the files as private to tripwire.
