hwdb is for: |
| 36 |
|
| 37 |
sys-fs/udev: read vendor/device string database and add it to udev |
| 38 |
database |
| 39 |
|
| 40 |
Evidently, if zlib is enabled then a file which udev needs to read to pull the |
| 41 |
vendor/device string will be zipped up and udev can't unzip or read it. |

Yeah but this error just occurred and I haven't recently installed anything |
| 47 |
which should have caused it, so I'm trying to figure out why the change. You |
| 48 |
can specify use files for one package but it's not usual, at least to my |
| 49 |
knowledge, just to get common packages to both be installed. |
| 50 |
|
| 51 |
I went the other route and disabled hwdb. |
