I wonder if we should be working out whatever dependancy issues we are having instead of forcing us to enable rest before we enable the Islandora module?

When I download a module I kind of expect to be able to drush en it without having to enable other modules first. Won't that be kind of confusing for folks installing islandora in the future?

Maybe I'm misunderstanding the issue. I'm always alarmed though, when we just force enable a module.

@jonathangreen Ah just seeing this comment now. Yeah, this is meant to be a short-term fix. Let's keep #643 open until we get it sorted out properly.

For context, we need to modify the rest resource config for nodes that the rest module provides. We can't provide our own because the two will conflict. So I'm editing it in hook_install right now, which probably isn't the best place. I'm loathe to introduce a hook_update_N to do something not related to an update at all. Do you know of a better place to do it?

@dannylamb so is rest not enabled by our drupal-project fork? I'm not understanding what module is not enabled when we try this?

[dannylamb]

@whikloj rest is installed when installing islandora since it's declared as a dependency. It can be pre-installed before installing islandora, so we needed to check that case as well.

But it's all moot at this point because I moved to using another hook. Instead of hook_install I'm using hook_modules_installed, which executes every time any module is installed, which covers both cases.
