[SAGE] Zones in Solaris 10 are based on FreeBSD Jails

[Scott Burch <scott.burch@camberwind.com>]

Wyatt,

In Solaris 10 you have Zones which are based on FreeBSD jails. You 
basically have one OS image and then you create a zone which you can 
boot in about 3 seconds. The zone is basically a chrooted bootable 
system that you can define devices for to mount other filesystems etc. 
Typically the the lib tree is mounted read only from the base OS. What 
Sun is doing with Solaris 10 is very interesting. You eventually will be 
able to download a build of Solaris 10 with Zones capability (Solaris 
Express), but I don't believe the current versions that are public have 
this capability yet. I have seen articles written about Zones, but I 
doubt you'll find much detailed information yet....however I have seen 
Zones demonsrated in engineering builds, so they are a reality.
