Smart move.

Permissions on /tmp ?

Should be 1777 (drwxrwxrwt).

To copy filesystems, I use:

  rsync -avxSHW --delete /var/ /mnt/var

This has the added benefit that you can copy most data over whilst the system is up and running.

Then you can take it down to single user, do the rsync again, and only the changed data will need to be copied.

This minimises the time the system is in single user (which is good if you are working on a server).
