 |
|
Hey all,
Should I install Coldplug and Hotplug if I compile my kernel manually?
I complied the vanilla 2.6.10 kernel following the install guide but I think I may have misread the Coldplug and Hotplug section uder the Genkernel section.
Thanks |

Coldplug is necesarry if you built your kernel with modules and want the modules loaded automatically at system boot. You can do the same thing if you list all the modules in /etc/modules.autoload.d/kernel-2.4.x
Hotplug is necessary if you want removable devices like usb sticks, cameras, etc... to have their modules loaded and devices created in /dev. It also is used by HAL, dbus, Gnome-volume-manager to automount these things and put a nice icon on your desktop. KDE is expected to move to this in the next realease but still uses hotplug. All PCMCIA must have hotplug installed in order to function.
If you don't need any of this functionality then don't install them.
If you use udev to manage your devices (and you should since devfs will no longer be included in kernels starting with 2.7) then you really should be using hotplug but agian, if you have no removable media of any kind then it is not strictly necessary.
I suggest reading the udev guide to help determine if you need hotplug/coldplug.

from the logs:
| Code: | bash-2.05b# cat /var/portage/2148-hotplug-20040923.log
* WARNING: The hotplug init script is now gone (dead and burried.)
* WARNING: If you want to load modules for hardware that was already
* WARNING: discovered at boot time, like the old hotplug init script
* WARNING: did, then emerge the coldplug package, and add coldplug to
* WARNING: a runlevel, e.g. # rc-update add coldplug boot
* WARNING: All firmware loaded by the hotplug scripts needs to be
* WARNING: moved to the /lib/firmware directory, as the scripts now
* WARNING: expect it to be in that location.
* If you still have the file /etc/hotplug/isapnp.rc on your system,
* please delete it by hand, the file /etc/hotplug/pnp.rc superseeds it.

its amazing what you can learn from setting PORT_LOGDIR in make.conf!
so amazing in fact, that I think they should suggest setting it up in the install docs...

Thanks guys for the info.
I installed udev and got it up and running. It really screwed up my Nvidia settings, but I was able to unmerge the Nvidia module and change some settings to prevent devfs from working within the system. After that I emerged Nvidia back onto the system and umerged devfsd.
Of course it took more steps than what I outlined above but now I am running a pure udev system. |
