IMO it is unreasonable to think that removing the whole /var/cache/forked-daapd directory can be deleted and is expected to be recreated because many services drop root privileges thus can't create dirs in /var/cache: total 64 drwxr-xr-x 16 root root 4096 Oct 6 20:56 . drwxr-xr-x 11 root root 4096 Sep 5 23:27 .. drwxr-xr-x 3 root root 4096 Sep 7 14:08 app-info drwxr-xr-x 3 root root 4096 Oct 6 20:56 apt drwxr-xr-x 2 root root 4096 Sep 7 14:08 cracklib drwxr-xr-x 2 root root 4096 Oct 5 09:25 debconf drwxr-xr-x 2 root root 4096 Sep 5 23:28 dictionaries-common drwxr-xr-x 2 root root 4096 Sep 8 20:40 fontconfig drwxr-xr-x 2 root root 4096 Feb 22 2016 fonts drwxr-xr-x 2 daapd root 4096 Oct 6 21:01 forked-daapd drwxr-xr-x 2 root root 4096 Aug 31 08:28 gdm drwx------ 2 root root 4096 Oct 6 20:56 ldconfig drwx--x--x 3 root root 4096 Sep 7 15:39 lightdm drwxr-sr-x 37 man root 4096 Oct 6 21:00 man drwxr-xr-x 3 root root 4096 Sep 7 14:08 PackageKit drwxr-xr-x 2 root root 4096 Aug 15 11:17 realmd In my interpretation of the FHS the _files_ can be removed and are expected to be recreated, while _directory structures_ need to be kept for applications to operate.
