I wonder if it could work with an LD_PRELOAD or some other linker trickery..
ie replace open()/read()/write() with something that looks for /etc/mtab and
instead opens /etc/fstab and translates it on the fly..
I don't use TSM though so I couldn't test it :)
(BTW linux_devtools can be used to make something like this, I wrote one for
the TeamSpeak port to hide an unimplemented sound ioctl)
