Bah! That's too slow for my taste. I would usually go for a newfs, dump, and restore option. For instance, to create a copy of /usr on a second disk: newfs -U /dev/ad1s1a mount /dev/ad1s1a /mnt dump -0 -a -L /usr | ( cd /mnt ; restore ruvf - ) Copying with dd(1) is not as fast :) _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
