-Program flow:
-
-* catalyst starts
-* it detects what machine type it is running on
-* it determines what machine targets it can build for (amd64 can build for
- x86 *and* amd64, for example.)
-* it loads the appropriate plugins from the arch/ directory, as modules
-* it registers each modules' classes with the main program so it can get
- to all the subarch classes supported by each module.
-
-todo:
-
-* it parses an incomplete spec file provided by the user
-* it generates a complete spec file and writes it to disk
-* it creates an instance of the appropriate subarch object, and passes the
- spec to the subarch so that it can build. (?)
-* the subarch ("builder") class does all building, snapshotting, etc.
-
-
-Classes are to be used to reduce code duplication *and* help maintainability.
-That's about it.
-
-Class heirarchy (preliminary):
-
-generic_builder (in arch/generic_builder.py)
- x86_generic_builder (in arch/x86.py)
- x86_builder (in arch/x86.py)
- pentium4_builder (in arch/x86.py)
- pentium4_builder.stage1()
- pentium4_builder.stage2()
- pentium4_builder.stage3()
- pentium4_builder.snapshot()
-
-stage1, stage2 and stage3 have almost identical set-up and break-down. What is
-different is what happens in the middle. steps are:
-
-* check for existing bind mounts at location (safety check)
-* clean chroot dir
-* chroot dir setup
-* unpack tarball to chroot dir
-* do bind mounts
-* chroot
-* execute script (bash)
-* exit chroot
-* umount bind mounts
-* grab goodies (variant: which goodies to grab and how (grp and livecds differ)
-
-purpose of builder modules:
- have code specific to each arch in its own file
- have common code in a generic parent class as much as possible
- (these both make maintenance easier)
-
-purpose of target modules:
- each target is going to need specific tweaks to various parts of the build process
- having a target module allows us to store these customizations in an organized way
-
-special things for targets:
- specify auxilliary mount points and where to mount them (for GRP packages)
- specify requirements?
