If you managed a set of servers running homegrown code that
may or may not be sensitive to library and utility program
versions, what steps would you use to keep a test server
up to date, then after performing any needed application
testing, to roll out the same changes to the production
servers in various different locations?  The object is to
install exactly the updates you just tested in spite of any
subsequent repository changes or out-of-sync mirrors.
