Symlink Question

[KP]

Hello All,

My /var file system will run out of space soon because of the database, I want to make a directory in /home (lots of space) and link it with /var/db. I want to know:

1. Should I use hard link or soft link for this case?
2. How to link it automatically upon reboot?
3. Any other issues should I concern?

Thanks in advance!
