I forgot to add that the ABE are reflected in your rpool which is one reason it is recommended to let rpool have the complete disk.   The ABEs just store the new bits compared to the BE that was active when you did the update.   There is a hierarchy but it is not much of an issue.   The beadm destroy manages the merging and the size will change to suit.  I have had 6 or 7 earlier BE's which have been destroyed with no problems.

ABE's are managed by the beadm command which is pretty simple.

   man beadm

Plus any time you run the "pkg image-update" (GUI or CLI)  it will automatically create the update in an ABE.   The "pkg image-update" command has a "--be-name <name>" option so you can define your own name rather than the default "opensolaris-1" etc.   The "pkg image-update" also sets the just created BE to be used at the next reboot by default.   The "beadm activate <name>" allows you to control that.

   man pkg

can you please give me the simplest procedure to install the alternat environment with 111b. I finally got a dual-boot config working on my notebook with a linux distro and don't want to screw it up...I am somewhat a newbie at this...Thanks

Can alternate boot environments be deleted later to save space too?
  

Yes   "beadm destroy <name>" <= Find name from "beadm list"


I would say test on your desktop but you will have to wait for build 131 to come out first since you cannot go backwards on creating builds.
