Whenever cfengine looks for a file it asks a question: is the filename
an absolute name (that is a name which begins from `/' like
/usr/file), is it a file in the directory in which you invoke
cfengine or is it a file which should be searched for in a special
place?
If you use an absolute filename either on the command line using
-f or in the import section of your program (a name which
begins with a slash '/'), then cfengine trusts the name of the file you
have given and treats it literally. If you specify the name of the
file as simple `.' then cfengine reads its input from the
standard input.
If you run cfengine without arguments (so that the default filename is
`cfengine.conf') or you specify a file without a leading slash in
the import section, then the value of the environment variable
CFINPUTS is prepended to the start of the file name. This allows
you to keep your configuration in a standard place, pointed to by
CFINPUTS. For example:
host# setenv CFINPUTS /usr/local/gnu/lib/cfengine/inputs host# cfengine -f myfile
In this example, cfengine tries to open
`/usr/local/gnu/lib/cfengine/inputs/myfile'.
