[gentoo-catalyst] filesystem not readable

[Lanza Fabrizio]

 Hi,
I'm using the last dev version of catalyst, r9. When my .iso was
completed and burned, I noticed that I can read the contents of the CD
only from linux. Windows cannot read it, and sees it as blank.
 I found that it was a bug, but I lost the link now.
 
 Does anybody know how I can fix this? Which packages does Catalyst use
in order to prepare the iso? If I update those, probably the error won't
happen any more.
 
 Thank you,
 Fabrizio
