SCO was pretty much pure SVR3, so noting that COMPAT_IBCS2 implements
SVR3 functionality is pretty much correct. Is anyone still using it?
I used it back-in-the day. I'm probably running some of the oldest Unix
variants and versions you'll run across. Also, where I work we support
legacy Unix platforms and we don't have any more SCO clients.
In my view "it's dead Jim". If we want to emulate a platform for Oracle,
I'd think the method dejour today would be Linux emulation.
Nowadays, I find that Unixware is a lot more interesting (free VxVM
anyone?) than SCO ever was. As you say, it was pretty much straight SysV
without many cool bells or whistles.
I also find SCO super-annoying now because it's so disagreeable about it's
licenses. It's tough to be more annoying than Tru64 about licenses, but
SCO manages. I know IT shouldn't be personal, but after we all watched
their public demise then Zombie SCO suing every FOSS company they could
left ashes in my mouth, personally.
I'm not anyone important in TNF, but I am a longtime user and user of
other platforms (SCO included) and my vote is to kill it and reduce the
kernel code size. :-)
