Appendix D. The sysconfig Directory
This appendix outlines some of the files and directories found in the

Note
The actual content of your
/etc/sysconfig/
directory depends on the programs you have installed on your machine. To find the name of the package the configuration file belongs to, type the following at a shell prompt:
~]$ yum provides /etc/sysconfig/filename
