# 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.
