bootstrap.lua

--[[
Root script for updater-ng configuration used for bootstrapping new root.

This script expects following variables to be possibly defined in environment:
  BOOTSTRAP_BOARD: board name (Mox|Omnia|Turris)
  BOOTSTRAP_BASE: optional specification of base script. 'base' is used in default.
  BOOTSTRAP_L10N: commas separated list of languages to be installed in root.
  BOOTSTRAP_PKGLISTS: commas separated list of package lists to be included in
    root. To specify options you can optionally add parentheses at the end of
    package name and list pipe separated options inside them. (ex:
    foo(opt1|opt2),fee)
  BOOTSTRAP_DRIVERS: comamas separated list of driver flags. Every driver class is
    combination of bus ('usb', 'pci' or 'sdio') and class itself separated by
    colon (ex: usb:foo,pci:fee). Special class 'all' can be used to include all
    drivers.
  BOOTSTRAP_CONTRACT: name of contract medkit is generated for. Do not specify for
    standard medkits
  BOOTSTRAP_TESTKEY: if defined non-empty then test kyes are included in
    installation
  BOOTSTRAP_INITIAL_CONFIG: if defined non-empty then package initial-config is
    included.
