  11 # There are two types of variables here which can easily be confused,
  12 # resulting in arbitrary bugs, mainly exposed with an offset
  13 # installation (Prefix).  The two types relate to the usage of
  14 # config_root or target_root.
  15 # The first, config_root (PORTAGE_CONFIGROOT), can be a path somewhere,
  16 # from which all derived paths need to be relative (e.g.
  17 # USER_CONFIG_PATH) without EPREFIX prepended in Prefix.  This means
  18 # config_root can for instance be set to "$HOME/my/config".  Obviously,
  19 # in such case it is not appropriate to prepend EPREFIX to derived
  20 # constants.  The default value of config_root is EPREFIX (in non-Prefix
  21 # the empty string) -- overriding the value loses the EPREFIX as one
  22 # would expect.
  23 # Second there is target_root (ROOT) which is used to install somewhere
  24 # completely else, in Prefix of limited use.  Because this is an offset
  25 # always given, the EPREFIX should always be applied in it, hence the
  26 # code always prefixes them with EROOT.
  27 # The variables in this file are grouped by config_root, target_root.
