It's probably a bit early for anything like deprecation. At this point, I think giving distributors the option of making it a symlink would be sufficient. My short term goal here is to allow the debian-installer to provide the option of merging / and /usr at install time by creating the symlink during initial bootstrap. The actual packages will continue to use /usr to permit use of a real /usr or a merged setup, so this should appear almost entirely transparent to both users and distribution packaging. It will require a full audit to idenfity duplicate/conflicting paths in / and /usr, and fixing them, plus fixing any tools which break due to e.g. library search paths causing confusion since all the contents of /usr/lib will also be in /lib--GNU/Hurd already supported this for years, but there may be regressions to address. WRT the need for embedded systems to have a separate /usr, I can't really comment on this having little embedded experience. Regards, Roger -- .''`.
