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/*
