I am using a Debian based live CD (GRML), and I trying to mount my main OS in the hard disk, FreeBSD 5.5, but everytime I try to do:

mount -t * /dev/sda /mnt/bsd

I get that the filesystem could not be recognised or somehing. NOTICE that where the * is it means I have tried ALL the filesystems I can think of.

The BSD hard disk is formatted as a UFS filesystem so obviously I have tried this one too. Is there a way of mounting a BSD system with Linux? What filesystem type should I use?
