[Fontconfig] Fontconfig cache in chroot

[Renáta Hodován]

Hi All!

I 'd like to chroot a process what uses fontconfig. For this reason I've 
hard linked my font directories (/etc/fonts, /etc/X11/fonts/, 
/usr/locale/share/fonts/, /usr/share/fonts/) and my fontconfig cache 
directories (/var/cache/fontconfig/ and $HOME/.fontconfig) into the 
sandbox directory. Unfortunately I experienced that fontconfig rebuilds 
its cache files inside the chroot (those what exist in the sandbox 
already). What's more nothing has changed (neither size, permissions not 
the owner of the cache files) except the last modification date ofc. 
This rebuild takes ~4-5sec what is too much :(
Do you have any idea what's wrong or how I can workaround this problem?

Thanks in advance,
Reni
