On my Lion system, /Library is still writable by owner, and a quick test reveals that an authenticated tool such as "su" is able to write files here. Existing installers also still seem able to write to /Library on my system. Is this a problem you have encountered with your own installer? Thanks for the clarification Paul! _______________________________________________ Do not post admin requests to the list. They will be ignored.

You might be thinking of the fact that ~/Library is now hidden in Lion. This doesn't change anything about how installers are allowed to modify ~/Library, but it does make it more difficult for users to manage their installed plugins via the Finder. On Lion, the user is discouraged from messing with ~/Library (although an experienced user can of course still access the folder in a variety of ways). However, all of the current install locations should still work on Lion. This email sent to site_archiver@lists.apple.com
