Yes this maybe true. However, if in the case this person has expertise
in AIX and IBM systems trying to bring in a Sun or HP system would be
counter productive from the stand point that then there would be
multiple Unixes to support and not all of the commands are the same and
because IBM has allot of it's own extensions to Unix trying to support
another unix is difficult because of the confusion in what is an AIX
extension and what is plan jane System V or BSD. Staying to one os is
limiting however it makes for much better support because you have the
expertise to deal with the system problems instead of a highly paid
phone jockey that lives for the help desk solution.
By the way Sun expects you to be a know it all for their Systems
anyway. If you don't there is that air of being very incompitent and
most people detest that air. I have had dealling with the support from
all three of the above and IBM seems to me to be the best of all of
them.
