mount_msdosfs: msdosfs_iconv: No such file or directory 怎么解决？

看下面：
f660:~#mount_msdosfs -L zh_CN.GB18030 /dev/ad1s1 /mnt/hdb1
mount_msdosfs: cannot find or load "msdosfs_iconv" kernel module
mount_msdosfs: msdosfs_iconv: No such file or directory
f660:~#mount_msdosfs -L zh_CN.eucCN /dev/ad1s1 /mnt/hdb1
mount_msdosfs: cannot find or load "msdosfs_iconv" kernel module
mount_msdosfs: msdosfs_iconv: No such file or directory
f660:~#mount_msdosfs /dev/ad1s1 /mnt/hdb1
f660:~#
这是怎么回事？

试试mount -t msdos

多谢，解决了。

Module loading has been fixed. Some older installations will
drop proper module_path initialization and modules will fail to
load properly. If you have a line in /boot/loader.rc that says:
"initialize drop", do (i386 only):
cp /usr/src/sys/boot/i386/loader/loader.rc /boot/loader.rc
chown root:wheel /boot/loader.rc
chmod 444 /boot/loader.rc
