fc3 mkisofs strangeness

[Jude DaShiell]

I was burning an image using mkisofs with the speakup version of fc3 and 
mkisofs threw a warning to the effect that /root/burn was unknown and 
unallocated but it was continuing on.  The image got burned and I'll find 
out later how good it was.  The mkisofs command I used came from use with 
an earlier version in the redhat line too.  The command was mkisofs 
-log-file=cdw2.log -r -J -o cd_image /root/burn <cr>.  /root/burn has a 
few directories in it of some binary files but more text files.  Is there 
a problem, and if so does a work-around exist?  I thought it might be 
-input-charset not having been set that might be messing things up but 
that didn't provide any help once it was set.
