Description Jan Beich freebsd_committer freebsd_triage 2016-05-23 05:52:41 UTC 
To facilitate mixing foreign executables with native in scripts image activators need to support path translation similar to linuxulator. This would make dynamic ELF executables able to find rtld(1) for their ABI without chroot. Once implemented the path can configured via an optional argument to binmiscctl(8).
