--- Comment #8 from André H. nerv@dawncrow.de 2010-09-12 11:17:06 CDT --- in the functions detecting if its a ramdisk it is hard to detect if they are actually detecting c:
i created a tmpfs mount in /media and chowned it to me, and it seems to work fine with firefox 4b5 and it's toolbar customization without any patching... i created it with: cd /media sudo mkdir bla sudo mount -t tmpfs -o size=500M,nr_inodes=5k,mode=0777 tmpfs bla cd .. sudo chown myusername bla
and used it like WINEPREFIX=/media/bla wine firefox_setup.exe
