[Voyage-linux] Modify Fstab

[Sean]

Varadarajan,

What I did to solve the home directory read only issue was to do these 
steps:

1. as root, remountrw.
2. log in as your unprivileged user.
3. get things set up the way you would like them.
4. log out from the unprivileged user.
5. log in as root.
6. cp -a /home/username /ro/username
7. rm -rf /home/username
8. ln -s /rw/username /home/username
9. restart

When the computer boots, /ro is copied to /rw in a memory filesystem. 
Now your user has a read-write home directory. Of course the contents of 
the home directory will be lost on poweroff. But you may want this in a 
kiosk situation.

If you want to keep the home directory then you will need to create a 
second rw partition. Then symbolically link the directory like I did in 
step 8.

Hope this helps!
