89: <p>
90: <b>Never install LON-CAPA-setup</b> on a running LON-CAPA machine.
91: This RPM package contains pre-installation files such as
92: /etc/group and /etc/passwd. You will lose all access to your
93: machine if you install this RPM.
94: </p>
95: <p>
96: If you are doing CVS-based upgrades of your LON-CAPA
97: software, then you do not need to upgrade your LON-CAPA-base
98: RPM. Upgrading with the LON-CAPA-base RPM
99: will cause you to lose many of your system-specific
100: configuration settings.
101: </p>
102: <p>
103: DO NOT UPGRADE YOUR KERNEL UNLESS YOU KNOW WHAT YOU ARE DOING.
104: Kernel upgrading involves packages beginning with the word
105: "kernel".
106: </p>

109: This file is generated dynamically by <tt>make rpmstatuspost</tt>

112: <p>
113: Managing software packages on any system, testing different
114: sets of software packages, tracking their dependencies, and maintaining
115: configuration information is an inexact science. While the LON-CAPA
116: recommended set of RPMs is a tested set with no missing dependencies,
117: we still highly recommend that RPM upgrades are only performed
118: by those with significant knowledge about standard Linux operating
119: systems.
