src/php.eselect.in.in: create symlinks relatively. |
9 |
|
10 |
As part of our $ROOT support, we need symlinks within $ROOT to point |
11 |
to stuff within $ROOT. The problem with that is that, if we create |
12 |
those symlinks with absolute paths, then you can't later chroot() into |
13 |
$ROOT and use them, because they'll point to the wrong place -- an |
14 |
absolute path that was only correct before you chrooted. |
15 |
|
16 |
Using relative symlinks seems to fix the problem, and shouldn't hurt |
17 |
anything in the common case where ROOT is unset or contains only a |
18 |
trailing slash. |
19 |
|
20 |
Thanks are due to Stefan Langenmaier for reporting the problem and |
21 |
helping us test the solution. |
