NetBSD 6.1.5 - man page for compat_osf1 (netbsd section 8)

     compat_osf1 -- setup procedure for running OSF/1 binaries

     NetBSD supports running OSF/1 (a.k.a Digital Unix, a.k.a. Tru64) binaries on NetBSD/alpha
     systems.  Most programs should work, including the ones that use the shared object
     libraries.  Programs that make direct MACH system calls will not work.  The OSF/1 compati-
     bility feature is active for kernels compiled with the COMPAT_OSF1 option enabled (see

     To run dynamically linked programs, you will need the OSF/1 shared libraries, runtime
     linker, and certain configuration files found in /etc.  These are installed in a ``shadow
     root'' directory called /emul/osf1.  Any file operations done by OSF/1 programs run under
     NetBSD will look in this directory first, and fall back to the file system proper.  So, if
     an OSF/1 program opens /etc/svc.conf, NetBSD will first try to open /emul/osf1/etc/svc.conf,
     and if that file does not exist it will then try /etc/svc.conf.  Shared libraries and con-
     figuration specific to OSF/1 should be installed in the shadow tree.

   Setting up /emul/osf1
     The simple technique is to install pkgsrc/emulators/osf1_lib.  (You may also want to install
     pkgsrc/www/navigator and/or pkgsrc/www/communicator.)

     Alternatively, if you have access to an OSF/1 machine and if the licensing details permit,
     you can copy the contents of:

     (The latter is required to run Netscape Navigator or Communicator.)

     Also copy

     Or, simply NFS mount the appropriate directories under /emul/osf1.

     config(1), options(4)

     Your hostname(1) must contain a dot or your resolv.conf(5) must contain a search line.
     Without one of those, the OSF/1 resolver will die and no hostname resolution will be possi-

     Certain values in /emul/osf1/etc/svc.conf can cause programs to fail with ``Bad system

     Pathnames pointed to by symbolic links are not looked up in the shadow root when running an
     OSF/1 executable.	This is not consistent.
