It will properly order installation so that dependencies are updated
first. However, it won't install newly required packages, which does
very occasionally happen. "yum update" will install newly required
packages; that's obviously a better solution. If I had a lot of Linux
boxes, I would definitely do that. For the past five years or so I've
been dealing with mostly 'dows with only one-off 'nix boxes, so I
haven't had need.
I had the "update requires a new package" thing hit me once or twice
before yum came out. I did one-off commands to handle it when it
showed up in the reports in the morning. For example:
for server in $( < servers.txt ) ; do ssh r...@${server} rpm
--install /pub/mirror/centos/5/updates/i386/RPMS/foo-1.2.3.i386.rpm ;
done
That uses SSH (secure shell) to run the package install command on a
list of servers.
SSH is kind of like PSEXEC but faster, works with any program, and
is safe over the public 'net. Putting it in a for loop is an
extremely common idiom in the 'nix world. If you have a lot of 'nix
boxes, look for pssh, which can run the commands in parallel.
