# Rebuild mit-zephyr on a 32-bit machine, like the one at Joe's home.

# Remember to set NSS_NONLOCAL_IGNORE=1 anytime you're setting up
# anything, e.g. using yum. Otherwise useradd will query LDAP in a stupid way
# that makes it hang forever.

# Install and configure bind
# - env NSS_NONLOCAL_IGNORE=1 yum install bind
# - chkconfig named on
# - service named start

# Reload the iptables config to take down the restrictive firewall 
# service iptables restart

# Copy over root's dotfiles from one of the other machines.

# Replace rsyslog with syslog-ng by doing:
# # rpm -e --nodeps rsyslog
# # yum install syslog-ng

# Install various dependencies of the scripts system, including syslog-ng,
# glibc-devel.i386, python-twisted-core, mod_fcgid, nrpe, nagios-plugins-all.

# Disable NetworkManager with chkconfig NetworkManager off. Configure
# networking on the front end and back end, and the routing table to send
# traffic over the back end. Make sure that chkconfig reports "network" on, so
# that the network will still be configured at next boot.

# Fix the openafs /usr/vice/etc <-> /etc/openafs mapping by changing
#  /usr/vice/etc/cacheinfo to contain:
#       /afs:/usr/vice/cache:10000000

# Figure out why Zephyr isn't working. Most recently, it was because there
# was a 64-bit RPM installed; remove it and install Joe's 32-bit one

# Install the full list of RPMs that users expect to be on the
# scripts.mit.edu servers.  See server/doc/rpm and
# server/doc/rpm_snapshot.  (Note that this is only a snapshot, and not
# all packages may in fact be in use.)

# Install the full list of perl modules that users expect to be on the
# scripts.mit.edu servers.  See server/doc/perl and
# server/doc/perl_snapshot.

# - export PERL_MM_USE_DEFAULT=1
# - Run 'cpan', accept the default configuration, and do 'o conf
#   prerequisites_policy follow'.
# - Parse the output of perldoc -u perllocal | grep head2 on an existing
#   server, and "notest install" them from the cpan prompt.

# Install the Python eggs and Ruby gems and PEAR/PECL doohickeys that are on
# the other scripts.mit.edu servers and do not have RPMs.
# - Look at /usr/lib/python2.5/site-packages for Python eggs and modules.
# - Look at `gem list` for Ruby gems.
# - Look at `pear list` for Pear fruits (or whatever they're called).

# echo 'import site, os.path; site.addsitedir(os.path.expanduser("~/lib/python2.5/site-packages"))' > /usr/lib/python2.5/site-packages/00scripts-home.pth

# Install the credentials (machine keytab, daemon.scripts keytab, SSL
# certs).

# If you are setting up a test server, pay attention to
# /etc/sysconfig/network-scripts and do not bind scripts' IP address.
# You will also need to modify /etc/ldap.conf, /etc/nss-ldapd.conf,
# /etc/openldap/ldap.conf, and /etc/httpd/conf.d/vhost_ldap.conf to
# use scripts.mit.edu instead of localhost.

# Install fedora-ds-base and set up replication (see ./HOWTO-SETUP-LDAP
#   and ./fedora-ds-enable-ssl-and-kerberos.diff).

# Make the services dirsrv, nslcd, nscd, postfix, and httpd start at
# boot. Run chkconfig to make sure the set of services to be run is
# correct.

# Run fmtutil-sys --all, which does something that makes TeX work.

# Ensure that PHP isn't broken:
# # mkdir /tmp/sessions
# # chmod 01777 /tmp/sessions

# Reboot the machine to restore a consistent state, in case you
# changed anything.

# (Optional) Beat your head against a wall.

# Possibly perform other steps that I've neglected to put in this
# document.
