Or you could do it this way:
1) Make a local mirror of the -current tree. For instance:
rsync -avz --del rsync://slackware.mirrors.tds.net/slackware/slackware-current /local/directory
2) Make an ISO image of it and burn it to a DVD -- I suppose you have a DVD writer:
Code:
cd /local/directory/slackware-current
mkisofs -o /tmp/slackware-dvd.iso -R -J -A "Slackware Install" \
-hide-rr-moved -v -d -N -no-emul-boot -boot-load-size 4 \
-boot-info-table -sort isolinux/iso.sort -b isolinux/isolinux.bin \
-c isolinux/isolinux.boot -V "SlackDVD" .
cd /tmp
growisofs -speed=2 -dvd-compat -Z /dev/dvd=slackware-dvd.iso
More information in the slackware-current/isolinux/README.TXT from which I borrowed above commands.
