I'm going to install Debian, Ubuntu and FreeBSD on my laptop. Is there a way to have a shared home partition for all three?

Depending on filesystem format, I would say just have the single /home partition mounted on each OS. – brandon927 Apr 4 '11 at 16:44

This is relatively easy to do. This and this might help. They give some good advice on how to make it work.

A little note an partitions:

There are 2 types of partitions, primary and logical.

  • You can only have up to 4 primary partitions.
  • You can have unlimited logical partitions

Make your /home/ partition a primary partition. Since you already have three, this will max you out. You may have problems with config file conflicts, so I would just mount a shared directory within each home directory to store common files. This can be done with fstab (change the path to your home directory).
