At first I have to say that I haven't used pca with LU personally yet; I 
do have reports from others who used it successfully, though.

The above method is the most simple way, and it should work. Another 
option would be to use pca together with 'luupgrade -t', which is the 
official command to apply patches to a BE with Live Upgrade (it uses 
"patchadd -R" to do the actual patching, just like "pca --rootdir" 
does), so it *shouldn't* make a difference.

You would use:

   pca --rootdir /<mounted BE> --download missing

to download (or list) the missing patches for the BE. Then create a 
patch_order file with:

   pca --rootdir /<mounted BE> --format "%p-%c" > patch_order

With a simple script, you can then unzip all patches and use "luupgrade 
-t -n ... -s ." to apply them.
