Hi, At the Utrecht BSP[1] we had some discussion about file paths, which is relevant for this bug as well. Here's what we found.
Summary: Package data should be in /usr/share; unpackaged data should be in /usr/local/share; configuration should be in /etc. Reasons: - /usr/share is owned by the system. That means packages can install things there, but the system administrator must not. Therefore it is not acceptable to require unpackaged themes to be installed there. - /etc has shared ownership; the system may add new files there, but may not destroy user changes. However, an extra limitation is that only config files should be there. (This forbids "put it in /etc".) - /usr/local/share is owned by the system administrator. Packages must not put any files there, other than a structure of empty directories (to help the system administrator putting the files in the right place). The FHS is pretty clear that this is the place where unpackaged add-ons (like drupal themes) should be installed.[2] - If data in /usr/share conflicts with data in /usr/local/share, the latter should take precedence. That way, the system administrator can override the package defaults. Now, if the package doesn't support this sort of behaviour, you should try to get as close as possible: - Put everything in /usr/share, but config files in /etc. Use symlinks to make the package understand it. - If possible, set up two theme folders (one for default themes in /usr/share, the other in /usr/local/share). If drupal doesn't support this, either add support for it, or dynamically add symlinks to /usr/share for themes installed in /usr/local/share, when the "please update my system"-link is used. A comment in the report mentions that it is desirable to be compatible with non-Debian installations. This is true. For this reason, I suggest two things: - Check how Drupal is normally installed on other systems. If this is compatible with the FHS, consider if this approach should be used for Debian as well. - If you need to add support for things, send it upstream and try to convince them that this is the Right Way to do it (using the FHS as proof). Thanks, Bas [1] http://wiki.debian.org/BSP/2012/10/nl/Utrecht [2] Literally: "Locally installed software must be placed within /usr/local rather than /usr [...]" Themes are clearly "software" in this context.
