Craig:
I'm not raising up against RPM packaging.  What I am concerned about is the
'migration' to a 'C:' drive in Linux.  Let me explain:
   Since you aren't telling me ahead of time where and how much space Java,
   Tomcat, or Apache is going to need, I have no choice but to make a very
   large '/' (root) partition which is the same as a 'C:' drive.  Except
   with M$, I can tell it to install on the 'D:' or 'E:' drive if I have
   one.
   Normally, since I haven't seen much go into /usr/local or /opt in the
   past (RH8-9, FC1-4), I usually make them around 512 MB in size.
   But now without any warning or documentation I may need a /usr/local or
   /opt of maybe 2-GB.


Les:
I use the standard 'sudo yum update' today without problems.
What I have learned is that , unless it was installed with a RPM package (I
download the Apache, Tomcat, and Java binaries as tar.gz packages), it
doesn't get updated.
