   Here's an easy way out. Boot from BeleniX 0.4.4 CD and execute

   df -h

   This will show you the exact device name of your FAT partition
   which will be mounted under /mnt/fatN. Now execute:

   cat /etc/vfstab

   From the output you can get the exact mount entry. Note it down
   and add it to your /etc/vfstab after booting from harddisk.

   Actually BeleniX 0.4.4 comes with the utility /usr/bin/partmgr
   that makes it easy to identify the mountable FAT partition device
   names using:

   /usr/bin/partmgr /dev/rdsk/cNdNp0 -doslabel

   This is automatically used during bootup of the LiveCD.

   It should mount automatically, if your USB pendrive is formatted as
   FAT. Also ensure that Volume Manager is running using:

   svcs volfs

   If this says "disabled" then execute:

   svcadm enable volfs.

   It is different though there are similarities as well. Someone has to
   port it.

   Linux kernel modules are GPL and cannot be simply ported to OpenSolaris
   and vice versa.
   It will be a violation of GPL. However userland stuff is fine. FUSE 
is being
   implemented on OpenSolaris which will allow userland filesystem modules
   to be ported onto OpenSolaris. See: 
http://www.opensolaris.org/os/project/fuse/

   ZFS has already been ported to Linux FUSE avoiding the licensing issues.
