--- Comment #20 from Dan Kegel dank@kegel.com 2012-07-09 05:10:44 CDT --- I tried
#include <windows.h> #include <stdio.h> int main(int argc, char **argv) { BOOL rv; char volname[1024]; volname[0] = '?'; volname[1] = 0; rv = GetVolumeInformation("D:\", volname, sizeof(volname), NULL, NULL, NULL, NULL, 0); printf("GVI returns %d, volname is %s\n", rv, volname); }
in a loop:
while true do wineserver -k rm -rf .wine wine vol.exe done
About 20% of the time, it prints GVI returns 0, volname is ? About 80% of the time, it prints GVI returns 1, volname is UDF Volume
Ubuntu thinks the volume name is "UDF Volume", too.
Meanwhile, the real volume name is: $ sh winetricks volnameof=/dev/sr0 FSX DISK 1
/usr/bin/volname gets it right, too (maybe https://bugs.launchpad.net/ubuntu/+source/eject/+bug/678419 is fixed).
Where is the bogus name coming from? $ udevadm info -q env -n /dev/sr0 | grep ID_FS_LABEL seems to be a pretty early point. strace says that gets it from /run/udev/data/b11:0 but I don't know who populates that file yet. "man udev" is somewhat intimidating.
