People who collect ISO images from more than just the FreeBSD Project have been mentioning it would be nice if “FreeBSD” was part of the filenames for a while now.

Ken Smith has committed a change that will add “FreeBSD-” to the beginning of the filenames.

So for example 9.0-RELEASE-amd64-dvd1.iso becomes FreeBSD-9.0-RELEASE-amd64-dvd1.iso
