Comment(by michael.klein@…):

 On my machine the cache seems completely ineffective with 2.9.0.

 Consecutive invocations of {{{fc-cache -v}}} give always the same output:
 {{{
 $ fc-cache -v
 /usr/share/fonts: skipping, no such directory
 /usr/X11/lib/X11/fonts: caching, new cache contents: 0 fonts, 10 dirs

 }}}

 While {{{fc-cache}}} runs, the file {{{$HOME/.fontconfig-be32d4.cache-3}}}
 is constantly being updated.  After that, inspecting that file with
 {{{strings}}} shows only fonts from
 {{{/Volumes/Users/michael/Library/Fonts}}}, but no other paths. The
 directory {{{$HOME/.fontconfig}}} is empty.

 If I pass {{{/Volumes/Users/michael/Library/Fonts}}} to {{{fc-cache}}}
 after {{{fc-cache}}}, the cache is found:
 {{{
 $ fc-cache -v /Volumes/Users/michael/Library/Fonts/
 /Volumes/Users/michael/Library/Fonts: skipping, existing cache is valid:
 43 fonts, 0 dirs
 /opt/local/var/cache/fontconfig: not cleaning unwritable cache directory
 /Volumes/Users/michael/.fontconfig: cleaning cache directory
 fc-cache: succeeded
 }}}

 For any other directory the cache is rebuilt.
