[已解决]挂载光盘，有乱码，文件名有中文的地方确不显示

wangjun.sh

今天把一个下载的电影刻录刻到光盘里。在 Windows XP下没有什么问题。可是在Gentoo下，却产生了乱码问题：
光盘的标签（Label）显示正常，里面的文件名有中文的地方确不显示。

如图下方左图“乱码”所示：

我的光驱在/dev/hdc, mount到/media/cdrom1。

我在/etc/fstab的设置为：

/dev/hdb        /media/cdrom0   udf,iso9660 user,noauto,utf8     0       0
/dev/hdc        /media/cdrom1   udf,iso9660 user,noauto,utf8     0       0
/dev/hdd        /media/cdrom2   udf,iso9660 user,noauto,utf8     0       0

mount信息如下：
$ mount
/dev/hda7 on / type ext3 (rw,errors=remount-ro)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec)
udev on /dev type tmpfs (rw,nosuid)
devpts on /dev/pts type devpts (rw,nosuid,noexec)
/dev/hda1 on /boot type ext3 (rw)
/dev/hda6 on /home type ext3 (rw)
/dev/hda3 on /mnt/Debian type ext3 (rw)
/dev/hda8 on /mnt/Archlinux type ext3 (rw)
/dev/hda9 on /mnt/LFS type ext3 (rw)
shm on /dev/shm type tmpfs (rw,noexec,nosuid,nodev)
usbfs on /proc/bus/usb type usbfs (rw,noexec,nosuid,devmode=0664,devgid=85)
/dev/sda1 on /media/JOHNWANG type vfat (rw,nosuid,nodev,shortname=lower,uid=1000,utf8)
/dev/sdb2 on /media/disk type ext3 (rw,nosuid,nodev)
/dev/sdb1 on /media/MOVE1 type ntfs (rw,nosuid,nodev,umask=222,utf8)
/dev/hdc on /media/cdrom1 type iso9660 (ro,noexec,nosuid,nodev,utf8,user=wangjun)

Volume 信息，如下方右图“volume”所示：

内核没有编好，
/usr/src/linux/.config中
CONFIG_FAT_FS=y
CONFIG_VFAT_FS=y
CONFIG_FAT_DEFAULT_CODEPAGE=936
CONFIG_FAT_DEFAULT_IOCHARSET="gb2312"
即可。

wangjun.sh

回去试试。
不过我的U盘，移动硬盘什么的都很好，没有这个问题。只是光盘有这个乱码。这个位置指定的也只是FAT的选项。会不会还有指定光盘的codepage的位置呢？

用其它的光盘有没有这样的问题呢?

我觉得应该是这两个选项：
CONFIG_NLS=y
CONFIG_NLS_DEFAULT="utf8"
我的fstab中的光盘设置：
/dev/cdrom              /mnt/cdrom      auto            noauto,user     0 0

我的:
CONFIG_NLS_DEFAULT="gb18030"
我以前cdrom不行的时候是
CONFIG_FAT_DEFAULT_IOCHARSET="gb18030"
改成
CONFIG_FAT_DEFAULT_IOCHARSET="gb2312"
就可以了。

thanks, acevery

我重新编译了内核，现在好了。

非常感谢。

请问一逻辑问题：cdrom和fat有嘛关系？又不用fat挂载～人家是iso9660或者udf~
