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.
