[OpenIndiana-discuss] Could you update your sysroot, jclulow?

[Till Wegmueller]

Use pkg image-create on a directory

then prepend "-R $IMAGE" to every pkg command.

Use pkg as normal but with -R (alternative root) flag directly after pkg 
to modify the newly created image instead of the system image (Currently 
running BE)
