Hi, A few days ago I posted a message about missing lost+found in /tmp of my fc3 system A. Now, I found more strange things: all folders under /tmp are missing: # ls -l /tmp/ total 0 The system log does not show anything related to /tmp. In my another testing fc3 system B, I have: # ls -l /tmp/ total 60 drwx------ 3 root root 4096 Mar 1 14:34 gconfd-root drwx------ 2 root root 4096 Mar 1 14:34 keyring-PuXOvH drwx------ 2 root root 16384 Dec 15 08:34 lost+found srwxr-xr-x 1 root root 0 Mar 1 14:35 mapping-root drwx------ 2 root root 4096 Mar 3 14:21 orbit-root drwx------ 2 root root 4096 Mar 1 14:34 ssh-dXnlyL5225 drwx------ 2 root root 4096 Feb 28 16:25 ssh-xtfeIp3820 (since it is a testing system, there is little activity). My questions are: the partition /tmp is always empty, will that cause any potential problem because those folders are missing? What are the purposes of folders gconfd-root, keyring-PuXOvH etc., as well as mapping-root, orbit-root? Is there any way to put /tmp back in the normal status? Thanks! Hongwei Li
