adapted to our current situation.

+.Dt COMPAT_OSF1 8
+.Os
+.Sh NAME
+.Nm compat_osf1
+.Nd setup procedure for running OSF/1 binaries
+.Sh DESCRIPTION
+.Ox
+supports running OSF/1 (a.k.a Digital Unix, a.k.a. Tru64) binaries on 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 compatibility feature is active for kernels compiled with the
+.Dv COMPAT_OSF1
+option enabled (see
+.Xr options 4 ) .
+.Pp
+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
+.Dq shadow root
+directory called
+.Pa /emul/osf1 .
+Any file operations done by OSF/1 programs run under
+.Nx
+will look in this directory first, and fall back to the file system proper.
+So, if an OSF/1 program opens
+.Pa /etc/svc.conf ,
+.Nx
+will first try to open
+.Pa /emul/osf1/etc/svc.conf ,
+and if that file does not exist it will then try
+.Pa /etc/svc.conf .
+Shared libraries and configuration specific to OSF/1 should be installed
+in the shadow tree.
+.Ss Setting up /emul/osf1
+You need access to an OSF/1 machine and if the licensing details permit,
+you need to copy the contents of:
+.Bl -item -compact -offset indent
+.It
+.Pa /shlib
+.It
+.Pa /usr/shlib
+.It
+.Pa /etc/sia
+.It
+.Pa /usr/lib/X11/locale
+.El
+.Pp
+(The latter is required to run Netscape Navigator or Communicator.)
+.Pp
+Also copy
+.Bl -item -compact -offset indent
+.It
+.Pa /etc/svc.conf
+.It
+.Pa /usr/ccs/lib/cmplrs/otabase/libots.so
+.It
+.Pa /sbin/loader
+.El
+.Pp
+Or, simply NFS mount the appropriate directories under
+.Pa /emul/osf1 .
+.Sh SEE ALSO
+.Xr options 4 ,
+.Xr config 8
+.Sh BUGS
+Your
+.Xr hostname 1
+.Em must
+contain a dot
+.Em or
+your
+.Xr resolv.conf 5
+must contain a
+.Li search
+line.
+Without one of those, the OSF/1 resolver will die and no hostname resolution
+will be possible.
+.Pp
+Certain values in
+.Pa /emul/osf1/etc/svc.conf
+can cause programs to fail with
+.Dq Bad system call .
+.Pp
+Pathnames pointed to by symbolic links are not looked up in the
+shadow root when running a OSF/1 executable.
+This is not consistent.
+.Pp
+Most Tru64 Unix (OSF/1 release 5) programs depend on an undocumented
+system call which is not currently supported.
