# Package:  Base
# Summary:  Functionality for downloading and merging extending
#    images for the inst-sys
# Authors:  Lukas Ocilka <locilka@suse.cz>
#
# $Id$
#
# This module provides functions that download inst-sys extension images
# (localization, fonts, ...) and merge them to the current int-sys.
# This enables inst-sys to be modular even for already running YaST.
# See FATE #302955: 'Split translations out of installation system'.
# This module is strictly installation-only!

      # **
      #
      # Paths where to download inst-sys extension images are taken
      # from '/etc/install.inf'. An extension image contains the
      # directory structure and files as it was in inst-sys but
      # it is a squashfs image of it.
      #
      # Inst-sys URL might be absolute or 'relative' to repo URL,
      # but only if instsys=... parameter wasn't explicitely defined.
      #
      #   When instsys=... parameter _is not_ used:
      #     * RepoURL: cd:/?device=sr0
      #     * InstsysURL: boot/<arch>/root
      #       (<arch> is for instance "i386", "x86_64", "ppc")
      #     or
      #     * RepoURL: nfs://server/repo/url/?device=eth0
      #     * InstsysURL: boot/<arch>/root
      #
      #   When instsys=... parameter _is_ used:
      #     * RepoURL: nfs://server/repo/url/
      #     * InstsysURL: http://server/inst-sys/url/
      #     or
      #     * RepoURL: cd:/?device=sr0
      #     * InstsysURL: nfs://server/inst-sys/url/?device=eth0
      #
      # Files to download are in the same level (directory) with
      # inst-sys:
      #
      #   * RepoURL: cd:/?device=sr0
      #   * InstsysURL: boot/<arch>/root
      #   -> cd:/boot/<arch>/$extension_file
      #
      #   * RepoURL: nfs://server/repo/url/?device=eth0
      #   * InstsysURL: http://server/inst-sys/url/?device=eth0
      #   -> http://server/inst-sys/$extension_file?device=eth0
      #
      # These files are always squashfs images that need to be:
      #
      #   * Downloaded: /lbin/wget -v $url $local_filename_path
      #   * Downloaded file needs to be checked against a SHA1
      #     hash defined in /content file
      #   * Mounted (-o loop) to a directory.
      #   * Directory needs to be merged into inst-sys by using
      #     `/lbin/lndir <image_mountpoint> /`
      #
      # This module remembers downloading a file so it does not
      # download any file twice.
      #
      # Additional comments on the "Installation Workflow":
      #
      #   * When Linuxrc starts loading an initial translation
      #     might already been selected. Linuxrc will download
      #     and merge the pre-selected translation itself.
      #   * Then Linuxrc starts YaST. YaST initializes itself
      #     including translations and displays the language
      #     dialog translated.
      #   * After a different language is selected, YaST downloads
      #     a localization inst-sys extension and merges it.
      #   * Then a different locale is selected and YaST redraws
      #     reruns the current YCP client.

101	# and merge the pre-selected translation itself.
102	# * Then Linuxrc starts YaST. YaST initializes itself

104	# dialog translated.
105	# * After a different language is selected, YaST downloads
106	# a localization inst-sys extension and merges it.
107	# * Then a different locale is selected and YaST redraws
108	# reruns the current YCP client.
