-.Dt COMPAT_SVR4 8
-.Os
-.Sh NAME
-.Nm compat_svr4
-.Nd setup for running SVR4/iBCS2 binaries under emulation
-.Sh DESCRIPTION
-.Ox
-supports running SVR4/iBCS2 binaries.
-This code has been tested on i386 and sparc systems.
-Most programs should work, but not ones that use or depend on:
-.Pp
-.Bl -tag -width 123 -compact -offset indent
-.It kernel internal data structures
-.It the /proc filesystem
-.It the ticotsord loopback rpc mechanism (NIS uses this)
-.It sound and video interfaces
-.It threads (ttsession uses threads)
-.It the streams administrative driver
-.It "mapping of page zero to the executable for Dell SVR4 binaries"
-.El
-.Pp
-The SVR4 compatibility feature is active
-for kernels compiled with the
-.Nm COMPAT_SVR4
-option and kern.emul.svr4
-.Xr sysctl 8
-enabled.
-.Pp
-Most SVR4 programs are dynamically linked.
-This means that the shared libraries that the programs depend on
-and the runtime linker are also needed.
-Additionally, a "shadow root" directory for SVR4 binaries
-on the
-.Ox
-system will have to be created.
-This directory is named
-.Pa /emul/svr4 .
-Any file operations done by SVR4 programs run under
-.Ox
-will look in this directory first.
-So, if a SVR4 program opens, for example,
-.Pa /etc/passwd ,
-.Ox
-will
-first try to open
-.Pa /emul/svr4/etc/passwd ,
-and if that does not exist open the `real'
-.Pa /etc/passwd file .
-It is recommended that SVR4 packages that include configuration
-files, etc., be installed under
-.Pa /emul/svr4 ,
-to avoid naming conflicts with possible
-.Ox
-counterparts.
-Shared libraries should also be installed in the shadow tree.
-.Pp
-The simplest way to set up the system for SVR4 binaries is:
-.Bl -tag -width 123 -compact
-.It 1.
-Make the necessary directories:
-.Bd -literal -offset indent
-(me@openbsd) mkdir -p /emul/svr4/{dev,etc}
-(me@openbsd) mkdir -p /emul/svr4/usr/{bin,lib}
-(me@openbsd) mkdir -p /emul/svr4/usr/openwin/{bin,lib}
-.Ed
-.Pp
-.It 2.
-Copy files from an SVR4 system:
-.Bd -literal -offset indent
-(me@svr4) cd /usr/lib
-(me@svr4) tar -cf -\ . | \e
-     rsh openbsd 'cd /emul/svr4/usr/lib; tar -xpf -'
-.Ed
-.Pp
-If OpenWindows is going to be run:
-.Bd -literal -offset indent
-(me@svr4) cd /usr/openwin/lib
-(me@svr4) tar -cf -\ . | \e
-     rsh openbsd 'cd /emul/svr4/usr/openwin/lib; tar -xpf -'
-.Ed
-.Pp
-.It 3.
-Set up the configuration files and devices:
-.Bd -literal -offset indent
-(me@openbsd) cd /usr/src/etc/etc.svr4
-(me@openbsd) cp netconfig nsswitch.conf /emul/svr4/etc
-(me@openbsd) cp SVR4_MAKEDEV /emul/svr4/dev
-(me@openbsd) cd /emul/svr4/dev; sh SVR4_MAKEDEV all
-.Ed
-.El
-.Pp
-An alternative method is to mount a whole SVR4 partition in
-.Pa /emul/svr4
-and then override with other mounts
-.Pa /emul/svr4/etc
-and
-.Pa /emul/svr4/dev .
-.Pp
-Clearly, a complete SVR4
-.Pa /dev
-directory cannot be used as
-.Pa /emul/svr4/dev ,
-because other device nodes, such as
-.Pa /dev/null ,
-need to be
-.Ox
-device nodes.
-.Sh BUGS
-Many system calls are still not emulated.
-The streams emulation is incomplete (socketpair does not work yet).
-.Pp
-Most SVR4 executables can not handle directory offset cookies > 32
-bits.
-More recent ones, compiled for large file support (Solaris 2.6 and up) can.
-With older programs, the message
-"svr4_getdents: dir offset too large for emulated program"
-will appear when this happens.
-Currently, this can only happen on NFS mounted filesystems, mounted from
-servers that return offsets with information in the upper 32 bits.
-These errors should rarely happen, but can be avoided by mounting this
-filesystem with the
-.Fl 2
-option to
-.Xr mount_nfs 8 .
