90: <p>
91: <b>Never install LON-CAPA-setup</b> on a running LON-CAPA machine.
92: This RPM package contains pre-installation files such as
93: /etc/group and /etc/passwd. You will lose all access to your
94: machine if you install this RPM.
95: </p>
96: <p>
97: If you are doing CVS-based upgrades of your LON-CAPA
98: software, then you do not need to upgrade your LON-CAPA-base
99: RPM. Upgrading with the LON-CAPA-base RPM
100: will cause you to lose many of your system-specific
101: configuration settings.
102: </p>
103: <p>
104: DO NOT UPGRADE YOUR KERNEL UNLESS YOU KNOW WHAT YOU ARE DOING.
105: Kernel upgrading involves packages beginning with the word
106: "kernel".
107: </p>
108: <font size="+2">About this file</font>
109: <p>
110: This file is generated dynamically by <tt>make rpmstatuspost</tt>

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