Comment 52 for bug 233942

I can confirm that the actual deb file (http://ppa.launchpad.net/ubuntu-burning/ubuntu/pool/main/c/cdrtools/mkisofs_2.01.01a50-0ubuntu1~ppa1~hardy_i386.deb) contains the binary, but it isn't actually installed.

$ COLUMNS=200 dpkg -l mkisofs

ii mkisofs 10:2.01.01a50-0ubuntu1~ppa1~hardy Creates ISO-9660 CD-ROM filesystem images

$ dpkg -L mkisofs | grep bin
/usr/bin
/usr/bin/isodebug
/usr/bin/mkhybrid

I don't know the details of deb files, but do they contain a list of files to be installed so that not all files in the package actually have to be used?
