RE: Linux in a sub-system?

[Vernon Hamberg <vhamberg@xxxxxxxxxxx>]

I think also that there is some kind of confusion here - the original 
BP especially - because there is no such thing as running Linux in a 
subsystem - only OS/400 objects can run in a subsystem, if you mean 
what we think of by one of those.

Now there is something called Virtual Partition Manager that gives 
you a logical partition through software - no extra hardware needed. 
And Linux can run in it. Last we looked was in 2005 or 2006 right 
after it was announced and it was not available then - we've not 
checked lately.
