Many years ago, I remember a Fedora upgrade (from version 4 to 5, I think) on a SATA disk on a Dual CPU PowerMac G5 (great machine at that time). The upgrade was progressing incredibly slow, and I was able to discover that every lib package upgrade was triggering ldconfig and spending a lot of time. So I renamed /sbin/ldconfig away (replaced with a stub or something), and speed went way up. After the RPM upgrade phase, I restored ldconfig and run it manually. When I proposed this kind of optimization in some mailing list (maybe this one?!), I was answered that my method was not entirely safe because there could have been problems for some rpm scripts calling libraries that had been just upgraded (e.g. perl libraries) without a proper ldconfig refresh. Was that a valid consideration? Has something changed on that front? I was convinced that ldconfig was a sort of cache, not critical to actually find libraries.
