[CentOS] yum update

Here, unpolished, is a script I used to use to
determine what changes I had made to an rpm-based
system. It requires a least light editing
(line 45, 49, and 52 at a minimum)
to run on CentOS; probably won't hurt anything.

# Summarize the key facts about the currently installed packages
# in a form useful for building a host with the same complement
# of packages. Creates 3 lists:
#   - the original install package list,
#   - packages that have been (upgraded/downgraded/added) 
#     but are from the same distributor
#   - packages that have been added from another distribution
#     or from free-standing rpm's

# TODO: identify packages built from tarballs, and either
#   - installed a new program not available in the distro, or
#     avail from the distro but not sourced from it.
#   - installed a program that was available from the distro,
#     but was (upgraded/downgraded/patched/built-from-source)
#     nonetheless.
#   Maybe build a list of all libraries / executables in
#   /bin, /sbin, /usr/bin, /usr/sbin, /usr/local/bin,
#   /lib, /usr/lib, /usr/local/lib, (etc?), then run through
#   rpm's official list (rpm -qal) using it to delete from
#   the first list. Anything remaining is unaccounted for by
#   the rpmdb, and may represent an "outboard" package.
#   Note that the file versions/dates will need to be checked,
#   and the possibility of multiple versions of the same
#   program should be handled.
