[ATrpms-users] Co-ordinating package versions on multiple systems (HOWTO?)

[Craig Huff]

I have a rather (I expect) basic question about the mechanics of
package installation.

If it makes any difference to the answer, I am currently using yum
under Fedora and/or CentOS, although I am thinking of at least trying
out smart thanks to Axel's often urging on this list.

I have a client-server package that I install on several systems
(MythTV, if you care) and they *should* be running the same exact
build to function properly, however...  Typically, they don't all get
done at one time and on occasion they end up with different builds.

My question is: How do I go about updating later systems with the same
.rpm that I used on earlier systems?  Is the .rpm that has been
installed on system A physically present there as a single file that
could easily be moved (e.g. with scp) to system B and then locally
referenced in the yum invocation (or better, referenced remotely from
A) on B?  If so, where should I expect to find the .rpm and how do I
tell yum to install /the/package/at/this/location/existing.rpm?

TIA

Craig.
