This is needed in order to be able to generate the cache on host.

Additionally, remove the volatile config file, as /var/cache was moved
out of tmpfs.

+Subject: [PATCH] Add sysroot option to fc-cache and fc-cat
+
+Whether one needs to generate the font cache offline and then deploy the
+image to a target or do some testing in a separate rootfs, the sysroot
+option will facilitate that.
+
+Suppose you've got a rootfs in the following directory:
+/path/to/test/rootfs. In order to contain the fc-cache generation to
+that particular directory, the following command can be used:
+
+fc-cache --sysroot=/path/to/test/rootfs
+
+That will make fc-cache to prepend the sysroot directory to all paths
+during scanning. For example, instead of searching /etc/fonts/ directory
+for configuration files, it will look in /path/to/test/rootfs/etc/fonts.
+The paths found in fonts.conf will also be prepended with the sysroot.
+
+However, the generated cache files will not contain any references to
+sysroot. This way, one can generate the font cache offline and then deploy
+the image to target. Or, simply, use it for various tests without
+polluting the system/user cache files.
+
+In order to inspect the cache generated using the sysroot option, one
+has to use fc-cat like below (for example):
+
+fc-cat --sysroot=/path/to/test/rootfs
+/path/to/test/rootfs/var/cache/fontconfig/*
