Hi, has it been noticed that jigdo-dlbd has exceeded the size of a single medium ? http://cdimage.debian.org/debian-cd/8.1.0/amd64/jigdo-dlbd/ http://cdimage.debian.org/debian-cd/8.1.0/i386/jigdo-dlbd/
I dimly remember that it was supposed to also serve as all-in-one ISO for large USB sticks or surplus HDDs. The next optical media size would be BD-R XL/TL with nominally 100 GB and BD-R XL/QL with nominally 128 GB. Did not see them yet. If they get not formatted and have 100.0e9 bytes, then one may assume at least 93 GiB of usable capacity. Subtracting 5 percent for formatted media: 88 GiB. Formatting and resulting size is at discretion of the user. If somebody has such a rare and costly specimen (under glass in protective atmosphere) the i'd be interested to see the outcome of a run of xorriso -outdev /dev/srX -list_formats Have a nice day :) Thomas
