I tried to download the Debian "testing" (aka "stretch) install media that is blu-ray because I wanted a one disk solution. When I went to the Debian site to download the blu-ray disk... there was 3 disks... arg.

The regular Debian dvd install media also has 3 disks. Given that the dvd and blu-ray install media both have 3 disks... what is the purpose of the blu-ray version?

  • What version of Debian are you trying to install? Stable, testing, unstable? And it would be extremely helpful if you could include the links where you found the DVD and Blu-ray images in question. – Faheem Mitha Jan 18 '16 at 23:20

    I'm voting to close this question as off-topic because it is about data storage formats... – jasonwryan Jan 19 '16 at 2:57

    This really doesn't seem to be about data storage formats at all. – Michael Homer Jan 19 '16 at 4:25

    @jasonwryan It's a question about Debian installation disks. Not about storage formats. Looks on-topic to me. – Faheem Mitha Jan 19 '16 at 4:46

    @jasonwryan Actually, the answer is, not all DVD images are available via HTTP. :-) He was asking why there appeared to be equal numbers of DVD and Blu-ray images, even though Blu-ray has a much bigger capacity. – Faheem Mitha Jan 19 '16 at 4:59

From #debian-boot on OFTC:

06:47 <musca> faheem: yes, the dvd series is much bigger, but only the first three images are available as http downloads. 
06:50 <musca> for stretch the number of DVD images is 15  http://cdimage.debian.org/cdimage/weekly-builds/amd64/jigdo-dvd/
06:55 <musca> faheem: let me point out: you really don't need those additional images.
  • So... Sounds the bd media require less disks? – Trevor Boyd Smith Jan 19 '16 at 3:01
  • @TrevorBoydSmith The first BR disk is a ton of stuff. Even the first DVD image would be a lot of stuff. What is your use case? Are you installing in Darkest Africa? :-) – Faheem Mitha Jan 19 '16 at 3:15
  • I like to install from media because then I can do multiple installs in <1 hour (install it one way... then learn something change my design/requirements... reinstall again... etc). Compared to the net installer which took about 4 hours for one install... over a 56mbps-tested connection. – Trevor Boyd Smith Jan 19 '16 at 16:25
  • @TrevorBoydSmith Ok. You must have remarkably fast optical and mass storage drives in that case. :-) – Faheem Mitha Jan 19 '16 at 17:00
