Ok. I'll do it for Mac only then. Regarding your "Why not?": this isn't possible. The user double clicks the application icon and doesn't pass any parameters. Regarding the surprise effects: the average user would be surprised in case LyX looses all the user settings on upgrade from 2.0 to 2.1 - especially on a Mac. The only solution I can imagine is to copy the preferences. The safest I can imagine is to copy them early - at the point when the new user directory is empty. And the easiest I can imagine is to implement this in configure.py without touching the LyX binary code. An additional build flag --inherit-settings is affordable but only when non-controversial. I should have given more explanation for the patch at first. Sorry about that. To summarize the facts what configure.py after the change is doing to migrate the user directory: 1) Check if the user directory is a new one. 2) Check for the user directory being 'LyX' + version suffix 3) Look for the neighbor user directories 'LyX-2.0' and 'LyX-1.6' 3a) and copying the first matching contents to the new user directory This effectively works on a Mac only, IMO. Some developers already pointed out the base name of the user directory on Linux is different. But to be sure I'll add an "if sys.platform == 'darwin':" making running on a Mac a prerequisite. Another prerequisite to enable the copying is the use of --with-version-suffix Stephan
