# This procedure is in development!!
# This is a procedure for automatic deployment/installation/configuration of systems. # TODO: document! (readme, notes about deployment profiles, examples, ...)
# check /usr/share/aif/examples for some example config files.
# This procedure can easily replace the old quickinst script if you look at the "generic install" config file
# Look at the base procedure to see the phases and which workers they'll execute.
# It should be:
# phase_preparation=(configure intro sysprep select_source runtime_network runtime_repositories runtime_packages)
# phase_basics=(set_clock prepare_disks)
# phase_system=(package_listTODO install_packages auto_fstab auto_networkTODO auto_locale configure_system mkinitcpio locales install_bootloader)
# phase_finish=(msg_report)

# In theory, the only manual thing should maybe be configuring the runtime network and putting the configfile in place
# TODO: I don't know if you can do non-interactive dm_crypt stuff.. maybe by pulling luks keyfiles from svn/git/..?
# TODO: for worker_configure_system, we probably want the user to specify hostname, root pass etc.

# for a list of recognized variables, see examples/generic-install-on-sda
