[pca] zones and $TMPDIR

[Rajiv Gunja]

Craig,
Please note that 'Update on attach' will only work for OS patches(this was
mentioned on Oracle's blog), it will not update Application patches if
present on the NGZ.

@ our office, we create LU environment and patch the GZ with NGZ using PCA.
We prefer this method over shutting down the server to single user mode, as
there was a bug which would not boot up the zones, back when zones were
still in infancy. Note: We use whole root zones and not sparse zones.

If you want to know how we do, drop me a line and I can send you our
process.

-GGR
