I presume you mean the 'root' user as determined during shell login.

While you can do this easily enough by a simple change to the /etc/passwd file it may not give you what you want. Reason: a limitation of FreeBSD and Linux (and all other POSIX compliant) operating systems, you can't tell the difference between which one logged in, or who owns files, or changes them. Because internally, the UID and GID are used, and what you see on your screen is only the first entry with that UID.

For example, here's an entry in one of my Linux systems:

jeff:x:1001:100:Jeff:/home/jeff:/bin/bash

Changing it to this means it has all the privileges and rights of root:

jeff:x:0:0:Jeff:/home/jeff:/bin/bash

let said i add user "surpassdns", how to make this user have the high permission, like restart services, reboot, etc

Find the line in /etc/passwd for that user; it will look something like this:

surpassdns:x:123:123:Jeff:/home/surpassdns:/bin/bash

and change those two sets of numbers (they most likely won't be 123 and may in fact not be the same) so it looks something like this:

surpassdns:x:0:0:Jeff:/home/surpass:/bin/bash

(do not change anything but the numbers)

But as I already wrote, you might as well just give out the root password, as the user will always be logged as root, and you won't be able to see the difference, in the logs, the directories, anywhere, anyway.
