Why do SCO/iBCS2 applications bomb on ``socksys''? (FreeBSD 3.0 and older only).

You first need to edit the /etc/sysconfig (or /etc/rc.conf, see rc.conf(5)) file in the last section to change the following variable to YES:

    # Set to YES if you want ibcs2 (SCO) emulation loaded at startup
    ibcs2=NO

It will load the ibcs2 kernel module at startup.

You will then need to set up /compat/ibcs2/dev to look like:

    lrwxr-xr-x  1 root  wheel         9 Oct 15 22:20 X0R@ -> /dev/null
    lrwxr-xr-x  1 root  wheel         7 Oct 15 22:20 nfsd@ -> socksys
    -rw-rw-r--  1 root  wheel         0 Oct 28 12:02 null
    lrwxr-xr-x  1 root  wheel         9 Oct 15 22:20 socksys@ -> /dev/null
    crw-rw-rw-  1 root  wheel   41,   1 Oct 15 22:14 spx

You just need socksys to go to /dev/null (see null(4)) to fake the open & close. The code in -CURRENT will handle the rest. This is much cleaner than the way it was done before. If you want the spx driver for a local socket X connection, define SPX_HACK when you compile the system.
