--- Comment #2 from Michael Gilbert michael.s.gilbert@gmail.com 2007-08-11 12:16:08 --- one solution would be for wine to automatically set up a dosdevice for each partition (cap it at 20 partitions max, otherwise we'll run out of drive letters).
although i just tried creating a dosdevice for /home/user, and steam now crashes, but this should probably be reported as a different bug.
$ cd /home/user/games/steam $ wine steam.exe runs fine $ ln -s /home/user/ "/home/user/.wine/dosdevices/y:" $ wine steam.exe crashes with error "Fatal Error: Could not load module 'bin/vgui2.dll'"
what do you think?
