In the course of discussing #4073, it dawned on me that Linux systems support icon themes, and typical
.desktopfiles enable this by using a symbolic name for their icons instead of an absolute path. So I spent a while reading up on how that works:Changes
.desktopfiles use the symbolic nameIcon=ckaninstead of the absolute pathIcon=/usr/share/icons/ckan.ico, to allow icon libraries to supply their own custom icons for CKAN/usr/share/icons/ckan.ico; instead, they install our variously sizedckan-16.png,ckan-32.png, ... ,ckan-256.pngfiles to/usr/share/icons/hicolor/16x16/apps/ckan.png(and so on for all the sizes), because this is the path for default application-supplied icons according to the spec
