Just installed RH7.1 (seawolf) on one of my boxes and, by default, it did not even install linuxconf. I did find that many of the other configuration util's were redone and much more useful. I may build linuxconf or install the RPM if I can find it, but so far I haven't needed it.
*TIP* if it's there, it should be in /sbin or /usr/sbin I believe. If it's there, you may have to type the full path to get it to run. I find I have to alter the PATH env. var. to get many things to run under root.
