Comment:
It is not only that triggers try to write to host root. Their executables are linked with dynamic libraries from host, eg. resulting in loud errors when installing other libc, and likely silent breakage when having outdated libraries in host.

Running triggers for alternative rootdir should be disabled at whole, I guess.
