Dual Booting LL 2.0 with other Ubuntu (14.04) based distros

[m654321]

Gold_finger, as you suggested, I filled up the gaps in the folder names in the bind-home.conf file (with hyphen), as well as in the /mnt/DATA and /home/m-ll2 folders. Following reboot, right-clicking on any of the folders in /home/m-ll2 indicates 924GB free so they appear to me to have all bound successfully to /mnt/DATA on the 1TB drive at sdb. I assume that's a correct asumption.  The only other thing on sdb is the swap partition (I abandoned a separate '/home' for each OS and have adopted the system that you more or less use. 

I ran the command 'ls -l /etc/init' in terminal and got the following output for bind-home.conf. I appear to have ownership by 'root' but, the file seems to have been duplicated, the difference being the tilde symbol following the second entry (see below). Should the second entry be deleted. How should I do this??

-rw-r--r-- 1 root root  864 Aug 25 05:56 bind-home.conf
-rw-r--r-- 1 root root  864 Aug 25 05:49 bind-home.conf~

You ask me a few things. I installed gedit and used this to create the upstart file, though think I might have used leafpad initially, so may still have an erroneous leafpad file floating out there (!) I did use sudo to open and edit the bind-home.conf file (I used terminal, not file manager) but now realize my error (thanks to your advice) and am now using gksu.

Many thanks for your continued support.
