That works, since I did upgrade just last weekend one machine from 8.2 
to cooker (or about 9.0 RC2).  Never tried upgrade from 8.1 remotely 
though.

If you have never done it, I would recommend first do an upgrade for a 
similar machine locally to see in which order to do things.  I have 
done in order 

1. glibc, and if remote, sshd
2. kernel and initscripts
3. reboot
4. rpm and urpmi plus some conflicting packages
5. --auto-select

When doing it remote, it is good to have a backup connection (like 
telnet) in case ssh upgrade fails.  Also in some versions I have 
observed that current ssh connections are killed when sshd is restarted 
after the upgrade--that is catastrophic if you are connected with ssh.

That is not too complicated process, having done it to three machines so 
far.  Step 4 needs some cleaning, since old 8.2 urpmi does not remove 
packages automatically, and there are some dependencies not up to date.
