# To make sure a sysext *replaces* a crate, rather than "merging" with it, we
# need to be able to set the 'trusted.overlay.opaque' xattr. Since we cannot do
# this as a user, we utilize `fakeroot` which keeps track of this for us, and
# turn the final directory into an 'erofs' file system image.
#
# The reason is that if a crate gets changed like this:
#
#     old:
#         src/foo.rs
#     new:
#         src/foo/mod.rs
#
# if its /usr/share/cargo/registry/$crate-$version directory was not marked as
# "opaque", the merged file system would end up with both
#
#         src/foo.rs
#         src/foo/mod.rs
#
# together.
