Dracut handling it well is not up for dispute. When I checked last year, |
| 14 |
dracut simply did not tell systemd to use this functionality because it |
| 15 |
was unnecessary functionality that only served to slowed down the |
| 16 |
shutdown process. It only enables it when a driver indicates an actual |
| 17 |
need, which is the way that it should be. |

Not many Gentoo users use dracut. It does not handle kernel compilation |
| 25 |
or bootloader configuration. It is definite ahead of genkernel in |
| 26 |
networking though, but there is not much demand for that among users. |
