Hard to believe such a tool doesn't exist somewhere. I needed
this yesterday and did it manually from a list made from `du'
output. If I ever have time I may write a perl script to do this
that would spit out mkisofs command lines.
The annoying part is that you can't give more than one path to
mkisofs. e.g. suppose you have 10 directories with 300 MB of
data in each, like
path/data 3GB
path/data/dir1 300MB
path/data/dir2 300MB
path/data/dir3 300MB
[etc]
You can't specify two of them to mkisofs. Instead you must go up
one level and exclude all the ones you don't want.

That would be interesting.
Probably possible to generate a file list with find, but AFAIK
mkisofs can't generate an image from such a file. Perhaps first
create a temporary tree using tar and then use mkisofs on that?

I'm interested, but unfortunately don't have much time.
