Well that's weird: I get nothing for lsof /var/tmp/portage. But if I do just lsof without |
| 22 |
args, I get hundreds of lines of output. Some of it looks like legitamte reports of open |
| 23 |
files for daemons I have running. But there are also many, many lines like below... all |
| 24 |
refering to non-existent files under /var/tmp/portage. |

Would love to hear what this is about. |
