But it does mean that you have to watch what yum is doing. Edwin also wrote: > 3.

The packages are quite at liberty to share (identical) files, including documentation files. This mostly works, but RPM will remove these files when only one package is removed, and it should not. See, for example, https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=164518 https://www.redhat.com/archives/fedora-devel-list/2007-June/msg02408.html which says: Expect memory use go up, dramatically. That's the price to pay for finally "fixing" the multilib %doc etc file removal bug by nuking the nasty skipDir hack that caused it to begin with. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=140055 (which suggests, again, that part of the internals of RPM will need to be rewritten to get memory use back down). The problem, I believe, is with the RPM libraries -- apt, smart and yum all use this code.
