## For what release to build images

# The suite the installed system will be based on
export CODENAME=lenny
# The suite from which the udebs for the installer will be taken (normally
# the same as CODENAME)
export DI_CODENAME=lenny


## The debian-installer images to use. This must match the suite (DI_CODENAME)
## from which udebs will be taken.
## Use *only one* of the next four settings. The "%ARCH%" placeholder in the
## 2nd and 4th options will be magically expanded at runtime.
## See also: tools/boot/<codename>/boot-$ARCH scripts.

# Use official images from the local mirror
export DI_DIST=$DI_CODENAME
# or, use official images from an outside mirror
#export DI_WWW_HOME="http://ftp.nl.debian.org/debian/dists/$DI_CODENAME/main/installer-%ARCH%/current/images/"
# or, use daily built d-i images (most from http://people.debian.org)
#export DI_WWW_HOME=default
# or, use custom / locally built images
#export DI_DIR="$HOME/d-i_images/%ARCH%"


## Other options

# Include local packages in the build
#export LOCAL=1
# Automatically update the Packages file(s) for the "local" repository?
#UPDATE_LOCAL=1

# Number of CD/DVDs to build; comment out to build full set
MAX_CDS=1
MAX_DVDS=1

# Only create the ISO files; don't create jigdo files
#MAXISOS=0
MAXJIGDOS=0


## Options that include CODENAME should be set here if needed, not in CONF.sh

# Include proposed-updates
#export PROPOSED_UPDATES=$CODENAME-proposed-updates

#export EXCLUDE1="$BASEDIR"/tasks/exclude-$CODENAME
#export UNEXCLUDE2="$BASEDIR"/tasks/unexclude-CD2-$CODENAME
#export UDEB_INCLUDE="$BASEDIR"/data/$CODENAME/udeb_include
#export UDEB_EXCLUDE="$BASEDIR"/data/$CODENAME/udeb_exclude
#export BASE_INCLUDE="$BASEDIR"/data/$CODENAME/base_include
#export BASE_EXCLUDE="$BASEDIR"/data/$CODENAME/base_exclude
#export SPLASHPNG="$BASEDIR/data/$CODENAME/splash-img.png"
#export RELEASE_NOTES_LOCATION="http://www.debian.org/releases/$CODENAME"


## The rest of the script should just work without any changes
