Do you want a slackware dvd containing both 32 and 64 bit packages using a normal dvd? (no dual layer, no dual side, no double face)
I written a script that create it.
You must to download both 32&64 dvd iso (and mount it) or slackware-tree (you may not download source/ directory). It support both -current and -stable versions.
Next you must modify the script configuration to adjust the path where are the slackware-tree and which packages do you want include.
ALL txz exceed the dvd size (about 4.8 GB).
You can choose:
1) exclude extra/ testing/ patch/ pasture/ . This fit into a dvd.
2) limit the languages supported (kdei and aspell)
# Where I can find slackware&slackware64 official tree
# May be the downloaded tree or premounted iso/dvd
# You must to limit which packages to include due fit in ONE dvd.
INCLUDE_EXTRA=yes # or yes
INCLUDE_PATCHES=yes # or yes
INCLUDE_PASTURE=yes # or yes
INCLUDE_TESTING=yes # or yes
INCLUDE_MISC=yes # or yes (misc/ is only on dvd, for 13.37)
INCLUDE_LOCALE="en es it fr en_GB" # or "" for all or "en" for none (you must install at least english :-)
Or you can download the prebuilt iso image from http://files.z01.eu/iso/
