Take a look at initng. It is really fast (if you compare to standard |
8 |
gentoo bootscripts). |

|

If that is not fast enough - take a look at software suspend. |

I was thinking of something similar some time ago. The idea was that if |
17 |
there is no /etc/modules run coldplug and list all loaded modules |
18 |
into /etc/modules, otherwise skip coldplug and just load the modules |
19 |
listed in /etc/modules. That would not detect if you have plugged a new |
20 |
USB device when powered off though. |
21 |
|
22 |
If you think that hotplugging is to slow (that there is a delay after |
23 |
you have plugged the external device until the device shows up) there is |
24 |
a hotplug-ng that is written in C instead of bash (like the standard |
25 |
hotplug system is). It is supposed to be faster. |

I think I posted an ebuild at bugzilla some time ago. |

You can try setting another background bitmap and background color in |
41 |
some resource file. The screen would be black or something while waiting |
42 |
for the backround image to show up. |
