not available when the package is removed, I find it more than likely that GTK+ or KDE are not there to benefit from icon cache updates any longer either. /usr/share may also be mounted read only with %_netsharedpath.
The right way to do things is to make sure touch is available by having an approiate script dependency on the package that provides touch. Something like: Requires(pre): coreutils
The point of the suggestion I posted is to avoid *unnecessary* dependencies like this one as well as unnecessary calls to touch and gtk-update-icon-cache. The part of my original message you quoted above explains why I think it doesn't matter if touch is available at %postun time or not (my assumption is that coreutils can't be removed while gtk2 or kdelibs is installed). If I'm correct and it doesn't matter, "Requires(postun): coreutils" is just unnecessary bloat in repodata, rpmdb and spec files.
