+This plugin prevents Yum from removing itself and other protected packages. |
| 25 |
+ |
| 26 |
+By default, yum is the only package protected, but by extension this |
| 27 |
+automatically protects everything on which yum depends (rpm, python, glibc, |
| 28 |
+and so on).Therefore, the plugin functions well even without |
| 29 |
+compiling careful lists of all important packages. |
| 30 |
+ |
| 31 |
+Additional packages to protect may be listed one per line in the file |
| 32 |
+/etc/sysconfig/protected-packages and in *.list files placed in |
| 33 |
+/etc/sysconfig/protected-packages.d/. |
| 34 |
+ |
| 35 |
+If you wish to temporarily exclude certain packages from protection, you can |
| 36 |
+use the --override-protection command-line option. |
