So, how about: - :a remains as it is today - :A when CHASE_DOTS set: same as :A today (resolves '..' first and symlinks second) - :A when CHASE_DOTS unset: as in the patch: equivalent to realpath(3) except that non-existing trailing path components are permitted Would that address everyone's concerns? Note this doesn't use CHASE_LINKS at all, neither in :A nor in :a. Mikael: I wasn't planning to push this until everyone has had ample opportunity to comment on the proposed change. Cheers, Daniel
