-## Soft-lock if `sccache` is preinstalled in chroot
-
-Apparently, some packages automatically use ccache/sccache if it is installed in
-the chroot, and in some cases, causes a soft-lock during a build. It is
-recommended to not have ccache/sccache preinstalled in the chroot and to just
-let the aur-helper-script install it when necessary.
-
-For example, when building `tenacity-git` with sccache preinstalled, the build
-will hang after the final build step. Apparently, killing the running `sccache`
-process stops the soft-lock in this case.
-
-## Preloading ccache/sccache
-
-This script expects ccache and sccache not to be installed in the chroot (for
-reasons as mentioned in the previous section) and ccache or sccache will be
-appended to a pkg's "other_deps" if a ccache or sccache directory is configured
-for it.

 the previous example.
