Hello, I am trying to install Gentoo.
Tried with genkernel

Or should I configure kernel manually ? Thank you for your suggestions. |

RIA77,
That's not a genkernel issue.
You need to accept the | Code: | | linux-fw-redistributable no-source-code |
licences to be able to install linux-firmware at all.
That's true if genkernel does it or you install it for any other reason.
Most USB devices and many video cards need firmware.
Alternatively, you can set USE=-firmware on sys-kernel/genkernel. The you don't get firmware in your initrd.
That may mean that things won't work as the firmware must be available when the kernel module that needs it is initialised.

Depends on how much you know/want to know about building kernels. I've never used genkernel, and from my viewpoint, it just seems to add a layer of potential confusion. But I'm sure genkernel regulars will find it significantly easier from their viewpoint.

RIA77,
If you need to ask, use genkernel and delay learning to configure you own kernel until kernel upgrade time.
Nobodies first attempt works. Your own kernel is the biggest Linux learning experience, so spread out the learning.

Au contrair. Mine did...of course it didn't occur to me that there might be configuring to be done. 70MB kernel. |

mrbassie,
Its the exception that proves the rule :)

| I remember building kernels back at the turn of the century and they were hard to make work first time. Now it seems like they are configuring the kernels (in the distro) to build first time. There's so much enjoyment in building kernels that will operate only on the hardware your building them for. As a gentoo user and only a gentoo user for 20 years, I say roll your own kernels and start today. |

This is the correct answer. Use genkernel for your first attempt. Once you have a working system move on to do it manually if you want. No reason going beyond what genkernel does automatically if you're just going to build a kernel that works no matter what. |

| Some time in the last year or so I discovered sys-kernel/gentoo-kernel and sys-kernel/gentoo-kernel-bin. I have not tried either but are there opinions in their context for a new user? |

Basically, it's so a new user can get a system booted the first go-round. You can either let the tool compile a generic kernel for you or grab one that's already been compiled. The -bin is like Funtoo although I don't know if it uses the Debian kernel like Funtoo.
Genkernel will build you a bloated but working config. You can trim it down later after you have a working system either with genkernel or the good old fashioned way. |

This is the rule I always use. When using a new board/system, I always use genkernel during the first install. The reason is because you can figure out what linux detected using the various tools (lspci, lm_sensors, etc). Plus, you always have a baseline kernel that is guaranteed to work. More often than not, you'll miss some part that causes your system booting problems. It's better to revert to a known working configuration rather than having to boot from install media to fix a problem. This rule has served me well over the years.

Genkernel did not detect my graphics driver (intel) in my first install causing X not to work - so I would say it is not a guarantee. Had to use menuconfig and enable a bunch of drivers  |

|

Long ago I tried genkernel once, and I agree, rolling your own is easier.
Boot from the minimal CD. Use lspci -k to get a list of the driver names for your hardware. In menuconfig, type the slash character(/), and enter the driver name. Use Location and Prompt to navigate in menuconfig, to enable the driver(and disable others).
Example for snd_hda_intel
| Code: | Symbol: SND_HDA_INTEL [=y]
Type: tristate
Defined at sound/pci/hda/Kconfig:14
Prompt: HD Audio PCI
Depends: SOUND [=y] && !UML && SND [=y] && SND_PCI [=y]
Location:
-> Device Drivers
-> Sound card support (SOUND [=y])
-> Advanced Linux Sound Architecture (SND [=y])
-> HD-Audio
|
Complete the list from lspci. Stopping here, will hopefully produce a bootable kernel the first time. Then tweak afterwards to correct or add to the kernel.
Alternatively, boot with Knoppix and get the kernel driver names from lspci. Sometimes the driver names vary, and investigating why can be a good learning experience. |
