Hi,

I'm currently moving data from one FreeBSD partition to another and noticed
that something is wrong with dump's diagnostic messages (notice > 100% and
negative times at the end of the dump):

root@notebook# mount -urf /
root@notebook# export TMPDIR=/mnt
root@notebook# pwd
/
root@notebook# cd /mnt/
root@notebook# dump -0 -f - / | restore -r -f -

This is a 3GB partition with a standard 5-CURRENT, several packages and my
development /usr/src and /usr/ports trees.

Any ideas?
