# Running

The build.sh and build_all.sh wrapper scripts are the easiest way to make CDs, but they're not very complicated.

## build.sh

This loads the configuration from CONF.sh, set some more default configuration (in case it's not already set in CONF.sh), then runs:

- `make distclean` - clean up after a previous run
- `make ${CODENAME}_status` - initialise the temp trees and seed the default set of base packages needed for the specified arch(es)
- `make mirrorcheck` - grab metadata from the mirror, used in generating jigdo files
- `make $IMAGETARGET` - will be the same as `make official_images` unless you've configured things differently. This is the step that actually builds images; more details later.
- `make imagesums` - generate md5sums of the completed images

### build.sh parameters

the single argument that build.sh takes is the architecture (or architectures) to build for. It will only build one set of CDs; if you specify more than one architecture as the parameter, the set will be multi-arch. Be aware, that to pass multiple arches as one parameter you need to specify them in quotes so the shell does not split them up, e.g.

`build.sh "i386 amd64 powerpc"`

## build_all.sh

build_all.sh is very similar to build_all.sh (deliberately). The only difference is that it will loop through a list of architectures, running each in turn and outputting them to a per-arch subdirectory in your output tree. That's all.
