Two different 2.11?

[Steven M. Schultz]

Greetings -

	No, there is only 1 2.11BSD (in the sense that there are NOT 
	competing versions or distributions).

	What happened I believe is that the Boot_Images/2.11_on_rl02 is older
	than the files in Distributions/ucb/2.11BSD.

	I have not looked at the Boot_Images/2.11_on_rl02 files to determine
	when they were created (what patch level, etc.).  On your RL02 system
	what do the first two or three lines of /VERSION?

	Anyhow, between the time that the 2.11_on_rl02 images were created
	(I did not create them) and December-1997/January-1998 several new
	system calls were created _AND_ the entire system was recompiled
	and relinked.  That is why you can NOT use binaries from the
	Distributions/ucb/2.11BSD with earlier kernels.  There is UPWARD
	compatibility (old binaries can run on new kernels) but not backwards
	compatibility.

	What you need to do is build a 'tape' (using 'makesimtape' if you
	need to use Bob's emulator) from ALL of the files in Distributions/ucb/
	2.11BSD.
