If I need to run Linux software, I can use an lx-branded zone inside of SmartOS, and run at the speed of bare metal while having ZFS, mdb, kdb, dbx and DTrace, CPU-bursting, and change kernel schedulers on the fly.

But then, as I am about to run Linux software inside of an lx-branded zone on SmartOS, I realize that SmartOS has 15,000 packages, with most the of the software I would have run on Linux, available natively on SmartOS:

...so then, which operational advantages would LX containers on Linux offer me, that I already do not have on SmartOS with zones?
