If so, are there consequences? Yes. FSCK will spew at you, and may digest your filesystem. I haven't tried this under 2.0.5, so the situation may have changed. There is _never_ a good reason to hard-link directories. Think about what would happen to a recursive-descent algorithm confronted with a directory linked to one of its parents. Having said that, as root you _can_ create a hard link to a directory. I'd do it just _after_ a backup. > ( -Wes Santee | You're never dead 'til you're ) -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] My car has "demand start" - Terry Lambert [[
