The files /var/log/netconf.log and /var/log/htmlaccess.log should be designed as log files in the spec file so that "rpm --verify linuxconf" doesn't report that there are problems with them.
Which version of the linuxconf package are you looking at? As of 1.18r7, the log files shouldn't even be in there....
I'm using linuxconf-1.18r4-1. I'll try a later version as soon as someone gets around to releasing a version of rpm-4.0 that actually works.
This is fixed in the current package.
