FreeBSD's disc1 image has surpassed 700MB, which is CD-ROM max size. dvd1 image is also almost at its limit, which is 4.7GB for single layer DVD (FreeBSD 14 dvd1 is 4541104128 bytes=4.54 GB).
In several years, FreeBSD images will surpass the limit for single-layer DVD, which means that the naming "disc1" and "dvd1" won't make sense anymore. I suggest to change the name of images such as -minimal and -full.
