 Update for FreeBSD 5.X
Author: dordal

Just a quick note to let you know that the procedure contributed by Dean at
the bottom of the page on no
longer works in FreeBSD 5.X.

The nice folks have updated the options that tar takes, and the correct
command is of the form:
tar --one-file-system -c -f - -C / . | tar xpvf - -C /mnt

tar --one-file-system -c -f - -C / . | tar xpvf - -C /mnt
tar --one-file-system -c -f - -C /var . | tar xpvf - -C /mnt/var
tar --one-file-system -c -f - -C /tmp . | tar xpvf - -C /mnt/tmp
tar --one-file-system -c -f - -C /usr . | tar xpvf - -C /mnt/usr

today i tried Dean's solution on my 6.1 PRE-RELEASE machine,

after 3 or 4 hours in hell, there are 2 things you should be noted:

1. if you mount your new disk at /mnt,
then /mnt should be excluded from tar,
otherwise, the /mnt/ directory will be tarred recursively.

2. use gtar, otherwise the permission of the directories (like /usr, /var!) will be a mess. (drwx---------, owned by root)
it's really strange. i hope it's just a temporary bug.

so, this is what i did

gtar cf - -C / --one-file-system --exclude /mnt/ . | gtar xpvf - -C /mnt/
