I use mkisofs 1.03 under NetBSD to generating my CDROM images. You should be
able to find it on lots of ftp sites.

Right, well this bit I do not do on a NetBSD box yet. I use a program called
cdwrite under Linux in single user mode. I just have not got round to getting
cdwrite compiled and running under NetBSD. The reason has been one of "If it
works, don't break it"
I use a fairly old writer (CDD521). I don't know about newer writers but once
you start a write you have keep the data flowing and cannot have any interrupts
otherwise the CDROM is trashed.
Oneday soon when I get round to improving the performance of the NetBSD/arm32
SCSI drivers I'll look at getting cdwrite to work under NetBSD.
Note: I have not really looked at what cdwrite actually does although the
source code is a very small program.
