Subject: Why is /run/vm/by-id/${VM} writable by the VMM?

This seems to be a fairly significant hole in the VMM's sandbox.
Various code operates in that directory and isn't secure against
symlink attacks.
Does the VMM really need write access to that directory? Could it
be given access to a subdirectory that is mounted "nosymfollow"?
