package apt retitle 566275 difference between src- and pkgcache.bin isn't documented thanks

It even lower the startup time, because: > Or maybe srcpkgcache.bin has a totally different meaning. It has. srcpkgcache.bin includes the information containing in the files in /var/lib/apt/lists - aka all informations you get from the internet by deb and deb-src lines -- these information are changed only on apt-get update. pkgcache.bin on the other hand caches the information in srcpkgcache.bin + the informations extracted from the apt and dpkg status files. These change on every install/remove done by apt or directly by dpkg. So if only the status files are changed apt doesn't need to reparse the other informations again - and if no file was changed in between yet and the last call apt can directly load the pkgcache.bin file into memory. > If so, this man page should say what it is. > Say what the two files track anyway here in any case. I am unsure if this should really be done. The manpages are already verbose (if not too verbose) on various topics and these options are rather lowlevel and not really commonly used, nor that i would expect that it would be widely used if it would be described to full extend. Such descriptions are in my eyes better suited for a manual, guide or other extra material...
