* this can be useful for passing extra parameters, pass
-v by default to see what's going on in do_rootfs
* we need to use this for extra parameter we implemented
in fontconfig:
--ignore-mtime always use cache file regardless of font directory mtime
because the checksum of fontcache generated in do_rootfs
doesn't match with /usr/share/fonts directory as seen on
target device causing fontconfig to re-create the cache
when fontconfig is used for first time or worse create
new cache in every user's home directory when /usr/
filesystem is read only and cache cannot be updated.
Running FC_DEBUG=16 fc-cache -v on such device shows:
FcCacheTimeValid dir "/usr/share/fonts" cache checksum 1441207803 dir
checksum 1441206149
* my guess is that the checksum is different, because pseudo
(which is unloaded when running qemuwrapper) or because some
influence of running the rootfs under qemu.
