Or help me in writing a good bug-report. |

The problem arise when using chrooted dhcpd, and disappear in a non |
| 4 |
chrooted environment. |
| 5 |
I'm intentioned in provide a decent bug report, please suggest other |
| 6 |
things that can be logged and provided. |
| 7 |
(would be nice to avoid expose dhcpd.log.*, they contain too much data ;) |

Thanks in advance. |
