Currently I run Darktable stable 2.6.2 on Ubuntu 18.04 and would like to try out a development version 2.7 without touching my current installation.
Coming from Windows I first thought of a portable app where I just start a binary and that’s all. But on Linux I am not familiar with such possibilities. After a quick search on the web I found ‘Appimage’ but I’m not capable of creating such an image.
I am not using a database for my images, just the XMP files.
I wonder if the unstable builds and the codebase itself should default to a different config directory anyway, e.g. .config/darktable-dev, to make it less easy to mess up the production database with experiments. Also, .xmp-dev files could be the default instead of .xmp. Only release builds (including candidates) would use the regular db and file extension then.
