I was under the impression that it was NOT recommended (by Novell)
that we install/upgrade the Novell client using ZENworks. Then I
came across a TID (10020605) that says otherwise. This TID is ~3-1/2
years old. Is it still OK to install or upgrade the Novell client using
ZENworks Desktop Management, and if so, do you know where I might find a
good article on setting that up?

We are currently upgrading our Novell clients via login script
running setupnw.exe /ACU /u:unattend.txt /SL:ACU_Status.log
