Yes, but I think the SunOS 4 shared library stuff was based on a.out,
I remember looking at the ld.so source code and thinking how simple
and elegant it all was, until those SysV people got their hands on it
and created ELF ;) What SysV release introduced ELF though?
cheers, Nick

Also as I understand it, SunOS was a BSD which

development and original ideas put into it (shared libraries I think
is one example), but was discarded as a political decision because
AT&T had managed to convince most corporate customers that BSD was
merely a hack and SysV was the "real unix", so Sun decided to create
Solaris instead by licensing SysV as a starting point, I may have
things slightly backward so I would appreciate if anyone can confirm
this?
I think that's basically correct, although in some technical sense "SunOS"
is still the name for the OS component of Solaris (or was until recently - Oracle have
probably renamed it), so you probably mean "SunOS n" where n<=4.
I think (though I am not sure) that a lot of the virtual memory and shared library stuff
which originated in SunOS 4 moved wholesale into SunOS 5, as well.
