231# Install the Python eggs and Ruby gems and PEAR/PECL doohickeys that are on
232# the other servers and do not have RPMs.
233# The general mode of operation will be to run the "list" command
234# on both servers, see what the differences are, check if those diffs
235# are packaged up as rpms, and install them (rpm if possible, native otherwise)
236# - Look at /usr/lib/python2.6/site-packages and
237#           /usr/lib64/python2.6/site-packages for Python eggs and modules.
238#   There will be a lot of gunk that was installed from packages;
239#   easy-install.pth will tell you what was easy_installed.
240#   First use 'yum search' to see if the relevant package is now available
241#   as an RPM, and install that if it is.  If not, then use easy_install.
242# - Look at `gem list` for Ruby gems.
243#   Again, use 'yum search' and prefer RPMs, but failing that, 'gem install'.
244#       ezyang: rspec-rails depends on rspec, and will override the Yum
245#       package, so... don't use that RPM yet
246# - Look at `pear list` for Pear fruits (or whatever they're called).
247#   Yet again, 'yum search' for RPMs before resorting to 'pear install'.  Note
248#   that for things in the beta repo, you'll need 'pear install package-beta'.
249#   (you might get complaints about the php_scripts module; ignore them)
250# - Look at `pecl list` for PECL things.  'yum search', and if you must,
251#   'pecl install' needed items.
252    # Automating this... will require a lot of batonning between
253    # the servers. Probably best way to do it is to write an actual
254    # script.

280#   o Replace the ssh host keys with the ones common to all scripts servers (real servers only)
281#   o You'll install an LDAP certificate signed by the scripts CA later (real servers only)
282#   o Make sure root's .k5login is correct
283    cat /root/.k5login
284#   o Make sure logview's .k5login is correct (real servers only)
286# If you are setting up a test server, pay attention to
287# /etc/sysconfig/network-scripts and do not bind scripts' IP address.
288# You will also need to modify:
289#   o /etc/ldap.conf

292#       replace: uri *****
