The trick I used in LinuxDefender (ftp://ftp.bitdefender.com/pub/linux/free/LinuxDefender) to mount as user knoppix is this:

Code:
mv /sbin/mount.captive-ntfs /sbin/mount1.captive-ntfs
Then create the file /sbin/mount.captive-ntfs with the contents:

Code:
#!/bin/sh

sudo /sbin/mount1.captive-ntfs $*
I also did this small modification in /sbin/mount.captive line 40:

Code:
$fsname=~s/^mount[.]captive-// or die "Cannot...
becomes
Code:
$fsname=~s/^mount1[.]captive-// or die "Cannot...
I know it's ugly, but it works, and I hope it helps.

Enjoy
