Only reading/writing the caches/fonts/config on the system directories.
i.e. if the caches needs to be updated, that requires the write access
to the system cache directory then. otherwise, fontconfig will tries
to read the caches on the system cache directories and show up the
fonts on the system fonts only. that said, correctly speaking, it just
affects FcConfigHome() behavior. if one writes the full path (without
using ~ of course) in the system's fonts.conf to somewhere on the user
directories, that will still be used.

Did it really work before?
fontconfig relies on FcConfigHome() to obtain the user's home
directory, FcConfigEnableHome(FcFalse) should applies to the caches,
config, and fonts then.
