Why did the App store grab the wrong disk? Was the updater also on the main disk? If not, seems like it did it right. Anyway, the update process is not always fully automatic; the disk for an update is usually chosen manually, unless it is a direct download from software update (and maybe from the App store).
I've shunned the App Store so far, but my understanding is that it doesn't allow you to maintain an archive; it searches every volume it can find and updates anything it finds that is subject to an update.
Remember, ganbustein said
"It did update the copy of "Install Mac OS X Lion.app" that I had squirreled away on a different volume where I thought it would be safe."Edit: The App Store performed as directed, if not necessarily expected; it
"grabbed the wrong disk" only in the sense that it affected a disk that ganbustein did not want touched.
