I installed Ubuntu 12.10 on my SSD. /dev/sda1. No other partitions. No swap.
Then I went about reading how to optimize usage, and have come to the conclusion I want my /home, /var and /tmp mounted on my hard disk drive. I don't have it mounted yet, but I have a line in my fstab that lists the UUID of my HDD and has it (/dev/sdb1) mounted in /media/hdd. Hard disk too, no partitions. Just plain disk space.
I do NOT want to create partitions on either my SSD or HDD. All I want however, is to move my /tmp, /home and /var partitions to my HDD.
What are my options to do this cleanly, preferably without using a LiveCD to login? (I am imagining I could use a LiveCD, literally do
mv /home /media/hdd/home ln -s /media/hdd/home /home mv /var /media/hdd/var ln -s /media/hdd/var /var mv /tmp /media/hdd/tmp ln -s /media/hdd/tmp /tmp
What about permissions?
Is my thinking correct? Can I somehow use a mount --bind option to achieve the same?
