It's Fluxbox Live 13.1.2, not 13.37 and so I now understand. This Live CD is old and is still using LLS, not SaLT, so this message is already gone, because there is already a new version of the way to make LiveCDs: SaLT.
Nobody made a live version for fluxbox 13.37 though. I could try to make one if you wish.
Live version of Salix 14...couple of weeks after Salix 14 will be out I suppose.
I still need to understand some weird bugs with isohybrid and/or usb3 on some configurations/materials.
