I am trying to setup a Haskell development environment and ran against a bump that's preventing me from completing the task. I mentioned this problem yesterday on IRC and got some help, but no definitive solution. The Haskell build tool is cabal, and after successfully installing the Haskell compiler (ghc-7.4.2) I want to update the build tool. But this step fails, and the log indicates that it cannot remove a temporary directory it created. I tried to remove it manually (rm -fr /tmp/foo as root) but it fails: rm: cannot remove '/tmp/foo': File exists but there is nothing in that directory. Here is the /tmp directory <pre>total 8126 drwxr-xr-x 23 root root 25 May 8 22:55 .. drwx------ 3 root root 117 May 9 13:23 cabal-install-1.16.0.2-21814 [...] drwxrwxrwt 8 root sys 925 May 9 16:07 . and here is the /tmp/cabal-install-1.16.0.2-21814 total 8 drwx------ 3 root root 117 May 9 13:23 . drwxrwxrwt 8 root sys 985 May 9 16:10 ..</pre> Some funny facts! If I try (as it was kindly suggested to me on IRC #omnios) unlink, then this works fine. If I try to zpool scrub, there is no problem. If I try to mkdir -m 0700 /tmp/bar; cd /tmp/bar; touch baz; cd /tmp; rm -fr bar it runs fine... If I reboot, /tmp dir is emptied fine. Below you'll find 1: the steps I used: 2: the output of the build log, with the error at the end 3: the output of truss when i execute rm -fr /tmp/foo Thanks for your help Matthieu <pre>Install a 'bloody' OmniOS from DVD.
