I was installing redhat 6.0 on a machine for dedicated name service so only selected the name service and network workstation software. rpm generated an inetd.conf file with ftp in it, but no in.ftpd was installed. ftp was installed. xfs was installed even though no X11 was requested as was alot of stuff in /usr/X11R6. A general suggestion is some type of help if you are seleting individual packages. many of hte names don't mean anything to me and I've been a unix admin (part time) for about 20 years. Its hard o tell what really is in some of the packages just from the package name.
The default inetd.conf has entries for services that may not be installed; it's normal. inetd will close connections to those ports xfs is installed, because some of the fonts that ghostcript uses need xfs to be used under X. X libs are installed because they're required for ghostscript.
