Perhaps you previously used a tool like ../pkgsrc/sysutils/dvd+rw-tools which supports a "growISOfs" feature that sort of mimics direct writing though it's just a wrapper around mkisofs ? You should be able to do all the steps manually by 1) copy current contents to temp dir 2) add or subtract files from temp dir 3) make a new ISO file system 4) burn new ISO filesystem to to the optical disc Years ago (2002 ?!) I made a hardcopy of the netbsd guide which covers writing an image to a CD/DVD in section 19 ; probably the info is still in the current version. HTH, -B
