Thanks!, some comments, though:

I tried it and it almost work, I think it is a bug too
because even if you are checking inside that directory, it doesn't
change the fact that is "mounted" per cfengine definitions.


Now, I say it almost work, because I tried setting:

   sensiblesize = ( 0 )
   sensiblecount = ( 0 )

but, sensiblecount has to be ' > 0 ' (per install.c)

   case cfscount:
                  sscanf(value,"%d",&number);
                  if (number > 0)
                     {
                     SENSIBLEFILECOUNT = number;
                     }
                  else
                     {
                     yyerror("Silly value for sensiblecount (must be positive 
integer)");
                     }

                  break;


so if I just create the directory, but don't place any
files/directories inside it, it won't be sensible for cfengine.

cfengine:myhost: Filesystem /home/.cfengine_freespace has only 0 
files/directories.
cfengine:myhost: The file /home/.cfengine_freespace does not exist or is 
suspicious.


Did you changed the source code to fix this?


The other option is to put some stuff inside the directory (I used
'copy' to put a file there), that way cfengine is satisfied, but if
you want to check a lot of filesystems, then you have to do this for
each one, and your config file grows a lot, I tried using iterating
over a list (i.e. var = (home:tmp:usr)) , but it doesn't work for all
the commands involved in this operation (i.e. directories, copy,
disks).

Thanks for your help.
