Q: El Capitan - Available for: Mac OS X v10.6.8 and later?

The description for many of the components being updated by El Capitan v10.11 says "Available for Mac OS X v10.6.8 and later". Does this mean it will install on OS X 10.6.8 and update these components without updating the system, or is this a complete system update? If its the latter, are updates for specific components available? I have a couple of machines using 10.6.8 Server which I'd like to install onto, but a complete system update would be incompatible with other software that's installed.

In any case, I was under the impression that it was necessary to upgrade to Lion before going on to Mavericks, Yosemite, etc. Does this upgrade bypass that step?

MacBook Pro (Retina, 15-inch, Mid 2014), OS X Mavericks (10.9.5)

Thanks, so that clarifies that its a full system update and which machines are supported - my old XServes can keep going that little bit longer! - although not whether its a one-step upgrade path. So, are updates for specific components available? Or is there a way of installing only those from the El Capitan installer?

For those that are interested incidentally, here's a copy of that list of supported machines (NB not all features may be supported):
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later), (12-inch, Early 2015)
MacBook Pro (13-inch, Mid-2009 or later), (15-inch, Mid/Late 2007 or later), (17-inch, Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac Mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)

If I understand you question, then no, you cannot update individual components of the OS.
You install the upgrade and everything is updated.
