@aus9:
Fluff works like this:
1) If ~/.fluff.conf file exists, Fluff opens it, reads the settings, then uses them to display the main window (window sizes, a set of file types and associations, some toolbar-related things, etc.)
2) If ~/.fluff.conf does not exist, these settings are set to default values, then Fluff uses those default values to present the main window (which includes an initial size that will fit in a 800x600 pixel display, a minimal set of file associations, etc.)
3) The user uses Fluff. Fluff tracks your changes in window size, how width of the directory tree window, file associations, whether to show "hidden" dot files, etc.
4) When the user closes Fluff, the file ~/.fluff.conf is created, or re-created with the current settings.
5) Your .fluff.conf file would normally be persistent if you do the normal backup of /home/tc or have a persistent home in your boot settings. So the next time Fluff starts, it will use the settings from the previous session. However, if home is not persistent, your Fluff settings would (of course) be lost and Fluff would re-create it again and again.
Therefore, if you go to look for the .fluff.conf file before you CLOSE Fluff the first time, you won't find it. I don't consider this a bug... it is just a side effect of a design decision.
If you want to see the default values, open fluff on a pristine base system then close it immediately. The settings in the .fluff.conf file will be the default settings. If you are trying to do something special regarding the .fluff.conf file or its settings, maybe PM and I will try to recommend a way to do what you want.
