I made a mistake. Please check and correct this in your
hardcopy. In the example for copying the home directories,
I wrote:
# mount -o ro /dev/ad0s1f /usr
# mount -o ro /dev/ad2s1e /home
The second -o ro is wrong, has to be -o rw, because
you're writing to this partition in the next step:
# mount -o ro /dev/ad0s1f /usr
# mount -o rw /dev/ad2s1e /home
The basic idea is to work with least dangerous
permissions, so if you're going to read files from
a partition, -o ro is sufficient. But of course it's
not sufficient for writing. :-)
And for the final /etc/fstab, this is wrong:
/dev/ad0s1d /tmp ufs rw 2 2
/dev/ad0s1e /scratch ufs rw 2 2
It would have to be:
/dev/ad0s1d /scratch ufs rw 2 2
/dev/ad0s1e /tmp ufs rw 2 2
becausse /dev/ad0s1d previously was /var.
In any case, as you're working with maximum privileges
on file systems, pay attention to device names and
directories. Triple-check them. Always.
