What is this mega-dvd-test?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fedora-14-Live-multi.iso is too large (5.2 gigabytes) for a normal DVD
with capacity of 4.7 gigabytes or so.  Aha! It must be intended for a USB
flash drive with capacity of 8GB or greater...

  [root@ryniker ryniker]# cmd/livecd-iso-to-disk --format --reset-mbr --overlay-size-mb 1024 --home-size-mb 1024 --unencrypted-home fedora/F14/Fedora-14-Live-multi.iso /dev/sdh1
  Verifying image...
  /home/ryniker/fedora/F14/Fedora-14-Live-multi.iso: Could not get pvd data
  Unable to read the disc checksum from the primary volume descriptor.
  This probably means the disc was created without adding the checksum.Are you SURE you want to continue?
  Press Enter to continue or ctrl-c to abort

  WARNING: THIS WILL DESTROY ANY DATA ON /dev/sdh!!!
  Press Enter to continue or ctrl-c to abort

Nope.  (Leap-before-you-look strategy fails in this case.)  What do we have here...

My guess is a work-in-progress, but also possible is I do not understand
the actual objective and consequently have tried to misuse this data.

I thought the notion was to construct a single DVD that would boot in
either i686 or x86_64 machines, then allow the user to select his
preference from four appearance choices.

JÃhann, do you have more information, perhaps a reference to something
that documents the goal of this mega-dvd effort?
