I would like the council to discuss the addition of three variables to |
| 7 |
EAPI3. |
| 8 |
|
| 9 |
- EPREFIX |
| 10 |
The offset prefix of a Gentoo Prefix installation. When Gentoo Prefix |
| 11 |
is not used, ${EPREFIX} should be "". |
| 12 |
This variable should be available everywhere. |
| 13 |
- EROOT |
| 14 |
The offset prefix appended to ${ROOT}, e.g. ${ROOT%/}${EPREFIX}/ |
| 15 |
This variable is available where ROOT is, following PMS: pkg_* |
| 16 |
- ED |
| 17 |
The offset prefix appended to ${D}, e.g. ${D%/}${EPREFIX}/ |
| 18 |
This variable is available where D is, following PMS: src_install |
| 19 |
|
| 20 |
While the first variable (EPREFIX) can be set using an eclass, the |
| 21 |
latter two need to be set by the package manager. In particular ED, |
| 22 |
because the value of D might not be known. EROOT and ED are convenience |
| 23 |
variables. Making them available already now, even though initialised |
| 24 |
as ROOT and D respectively, allows Prefix enabled ebuilds to be shared |
| 25 |
between gentoo-x86 and Prefix trees without modifications. |
