Is cdrom30.fs == /bsd ?

[Alexander_(_dot_)_Farber_(_at_)_t-online_(_dot_)_de (A. Farber)]

Hi,

I'm copying some of my private files to a CD and wonder if I can 
also make that CD bootable by "mkhybrid -b cdrom30.fs ..."

And will "mkhybrid -b /bsd ..." also work? If not, how is the 
cdrom30.fs made and how do I make my own (with my custom kernel)?

Thanks
Alex
