Compensate for default disabling of network services in inetd.conf(5) by providing the opportunity to edit inetd.conf during the system installation process. The following modifications were made: (1) Expand the Anonymous FTP description dialog to indicate that inetd and ftpd must be enabled before it can be used. (2) Introduce a new configInetd() pair of dialogs, the first describing inetd, giving a couple of examples of services that require it, and hinting at potential risk, then asking the user if they wish to enable it. The second indicates that inetd.conf must be configured to enabled specific services, and asks if the user would like to load inetd.conf into the editor to modify it. Add this configuration action to the index. There are some further improvements that might be considered: (1) Provide a more inetd.conf-specific configuration tool that speaks inetd.conf(5). However, this is made difficult by the "yet another configuration format" nature of inetd.conf, as well as its use of commenting to disable services, rather than an in-syntax way to disable a service without commenting it out. Submissions here would probably be welcome. (2) There's some overlap between settings in the somewhat obtuse Security Profile mechanism and other settings, including the inetd setting, and NFS server configuration. As features become individually tunable, they should probably be removed from the security profile mechanism. Otherwise, somewhat counter-intuitively, sysinstall (in practice) queries multiple times whether inetd, nfsd, etc, should be enabled/disabled. A possible future direction might be to drive profiles not by degree of paranoia, rather, the set of services desired. Or simply to remove the Security Profile mechanism and resort to feature-driven configuration. Reviewed by: imp, chris, jake, nate, -arch, -stable

- Rename installFixupBin to installFixupBase to finish up the 'bin' to 'base' dist rename. - Rework struct dist to allow for different types of dists. There are currently three types of dists: DT_TARBALL, the traditonal gzipped and split tar file; DT_PACKAGE, a package; and DT_SUBDIST, a meta-dist in the tree that has its own array of dists as its contents. For example, the 'base' dist is a DT_TARBALL dist, the 'perl' dist is a DT_PACKAGE dist, and the 'src' dist is a DT_SUBDIST dist with its own dist table that contains 'sbase', 'ssys', etc. - Add helper macros for defining array entries for the different types of dists to try and make the statically defined dist table in dist.c more readable. - Split the logic to deal with a DT_TARBALL dist out of distExtract() and into its own distExtractTarball() function. distExtract() now calls other functions to extract each dist. - Tweak the percentage complete calculation in distExtractTarball() to do the multiply prior to the divide so it doesn't have to use floating point. - Axe the installPackage() function along with the special handling for the perl and XFree86 dists in distExtractAll() since distExtract() handles package dists directly now. - Add back in subdists for the X packages based on the split up packages that XFree86-4 uses that as closely map to the X dists we used with X 3.3.x. - Lots of things like distSetX() and the X dist masks are no longer #ifndef X_AS_PKG since we use them in both cases now. - Make the entire installFixupXFree() function #ifndef X_AS_PKG, we only call it in that case anyways, and it's not suitable for the X_AS_PKG case. - Add in X dist menus for the X_AS_PKG case.
