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