# This script creates a live image for a Slackware OS.
# Features:
# - boots using isolinux/extlinux on BIOS, or grub on UEFI.
# - requires kernel >= 4.0 which supports multiple lower layers in overlay
# - uses squashfs to create compressed modules out of directory trees
# - uses overlayfs to bind multiple squashfs modules together
# - you can add your own modules into ./addons/ or ./optional subdirectories.
# - persistence is enabled when writing the ISO to USB stick using iso2usb.sh.
# - LUKS encrypted homedirectory is optional on USB stick using iso2usb.sh.
#

# Version of the Live OS generator:

# If you want to include an EFI boot image for 32bit Slackware then you
# need a recompiled grub which supports 32bit EFI (Slackware's grub will not).
# A patch for grub.SlackBuild to enable this feature can be found
