I haven't got anything particularly new to add to the discussion here. But I would like to refer you to the previous discussion on the topic. I am well aware that the default does not satisfy all use cases, but that's simply not possible for this problem. The best we can do is have a good default. That could be by improving the tmpfs default sizes and behaviour (my preferred solution). It could be by defaulting to not using a tmpfs. However, the majority of software which finds the tmpfs too small has unreasonable expectations of what can be expected to be available (by default). http://lists.debian.org/debian-devel/2011/04/msg00554.html http://lists.debian.org/debian-devel/2011/11/msg00281.html http://lists.debian.org/debian-devel/2012/02/msg00473.html http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=630615 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=630615#50 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=630615#89 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=665406 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=674517 http://fedoraproject.org/w/index.php?title=Features/tmp-on-tmpfs Also see sysvinit in experimental. > And the most important thing: file managers, browsers, image editors, > cd burners — these are not some rare scientific stuff, but a common > programs, that most people use every day.

But I lacked the time and familiarity with the d-i code, and the d-i developers also have higher priorities. I'm sure support for tmpfs in the partitioner would be welcome if you want to add this functionality. Regards, Roger -- .''`.
