Likely sensord does a lot more than recording to syslog. |

rrdtools is used as a database but also used to build graphs from its |
| 48 |
database, which probably explains cairo. Cairo is a graphics library |
| 49 |
that can render to multiple devices including X11. |
| 50 |
|
| 51 |
If you want you can submit a patched ebuild for rrdtool that maybe uses |
| 52 |
a cairo USE flag and clearly separates the graphics system from the |
| 53 |
database system. You'll probably need to work closely with upstream for |
| 54 |
that. |
