I'm no stranger to Drupal, but I have no experience with custom installation profiles.
First, are custom installation profiles supposed to be overwritten when core is updated?
I've inherited a Drupal 7 site that has a pretty complex and very custom installation profile complete with modules dir (contrib and custom) themes dir, custom libraries, etc... it looks like they tried to fit an entire drupal site structure in here. Let's say that one is called Custom1.
Another installation profile Guardr is also in the profiles directory. Guardr is actively community supported.
The Drupal documents for distributions state that only one profile can be installed at a time and cannot be combined with other profiles.
Yet the hook_install function of Custom1, the first thing it does is call !function_exists('guardr_install') ? require_once 'profiles/guardr/guardr.install : FALSE; call_user_func('guardr_install');
That doesn't feel right given what I've come to understand about installation profiles. Moreover, in the /Profiles/Custom1/modules/contrib directory, there has to be 100 of the most popular contrib modules here, like addressfield, ctools.... (and sites/all/modules/contrib is empty) I can understand a profile requiring a certain set of modules, but isn't that the job of the dependencies[] array in the profile.info file?
In any case, my understanding is that an installation profile is called at the very beginning of the installation process and once it's finished, it's a 'typical' Drupal site that I can manage, update, etc, from that point on.
Now when I call drush up the profiles directory is overwritten and only standard and minimal profiles are there. This completely breaks the site because 90% of the functionality is tied to the modules, libraries, themes, and other files in both the Custom1 and Guardr profiles directories.
It's either the case that this is an example of perhaps not the best way to use installation profiles, or I don't understand profiles well enough to manage a site that has them deeply embedded.
If it's the latter, how do I upgrade the site so that it doesn't fubar it?
