Multiple binary CD-ROMs + + . Multiple binary CD-ROMs, accessed through NFS + + . Multiple binary CD-ROMs, pre-mounted + +Acquiring package data +--------------------- + + Since this method is derived from the 'mounted' method the user is + able to access up to five binary directories within 'dists/stable': + + . main + . contrib + . non-free + . local + + The selected method will try to read the 'Packages.cd' file from each + of these directories if it is available. + +Identifying the CD-ROM +---------------------- + + A unique name is associated to each CD. This name should correspond + with the label on the front of the CD. The name is also available on + the CD, so the system can find out which CD is in the drive at any + time. + +Installing the files +-------------------- + + At the beginning of the installation the 'multicd' package will sort + the list of to-be-installed packages and install them CD by CD. If a + different CD-ROM is required the user will be prompted to exchange + the CD-ROM. + +Preparing multiple binary CD-ROMs +--------------------------------- + + Since the 'multicd' methods need to know which packages are on which + CD-ROMs one cannot use regular 'Packages' files. An additional data + field "X-Medium:" is required. The first CD-ROM from the set should + contain all 'Packages.cd' files. To be more convenient you should + include the 'Packages.cd' files on all CD-ROMs. This ensures that + you don't have to start with the first CD-ROM all the time. + + Additionally the package needs to gain information which CD-ROM is + currently used. Thus each CD-ROM contains the file '.disk/info' + which contains the symbolic name for the CD-ROM as specified by + "X-Medium:". + + In order to be able to create the modified 'Packages.cd' files, you + have to use the '-M medium' option of dpkg-scanpackages (supported + in dpkg-dev >= 1.15.5). + + To split the 'main' distribution into two CD-ROMs you'll need to + create a 'Packages.cd' file for each 'binary-$arch' directory. + Afterwards you simply append the second one to the first one and + put the resulting 'Packages.cd' file into both 'binary-$arch' + directories. + +Sample Layout +------------- + + CD1 .disk/info = "Debian GNU/Linux binary-i386" + dists/stable/main/binary-all/ + binary-i386/Packages.cd.gz + binary-i386/net/foo.deb + contrib/binary-i386/Packages.cd.gz + non-free/binary-i386/Packages.cd.gz + + CD2 .disk/info = "Debian GNU/Linux contrib-i386" + dists/stable/main/binary-i386/Packages.cd.gz + contrib/binary-all/ + binary-i386/Packages.cd.gz + binary-i386/net/foo.deb + non-free/binary-i386/Packages.cd.gz + + CD3 .disk/info = "Debian GNU/Linux non-free-i386" + dists/stable/main/binary-i386/Packages.cd.gz + contrib/binary-i386/Packages.cd.gz + non-free/binary-all/ + binary-i386/Packages.cd.gz + binary-i386/net/foo.deb + + To re-generate the Packages file you have to chdir into + 'dists/stable/$part' and issue 'dpkg-scanpackages' as follows.
