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.
