Last questions before installing Gentoo

[Thranduil]

hi all,

all this question are related to the official gentoo.org - Installation Guide
Official Installation Guide

I hope you can help me

1.) Chapter 7. - from Code Listing 2 on

What commands must I use, if I want to install Kernel 2.6 instead of 2.4? Can i do this with the vanilla version? What must I notice? etc. - all differences between the documentation and the 2.6 kernel - install plz

2.) How can I read one variable ("IUSE_VIDEO_CARDS") from the file "/usr/portage/x11-base/xfree-drm" during the installation?

3.) Chapter 8. - Code Listing 5

What must I add, if I want to "install" my cd-burner/writer (dont know if this is the correct english term ) next to my cd-rom-drive ?

4.) Chapter 9 - Code Listing 5

If I have my root dir at /dev/hda1 - then it is hd0,0 !! What is the hd0,x - number for other /dev/hda's - for example for /dev/hda7 ??

I hope I've explained everything correctly

greetings
Thran

P.S: Please explain everything in detail and for "normal-noob-users" understandably...[/url]

Hi,
can't help with the kernel question

For question 2. At what point do you want to read the variable and is it exported? (I guess so?) Something as simple as

Code: Select all

echo $IUSE_VIDEO_CARDS

could do the trick?
If you have a cd writer it should appear in Linux, there is no installing as such. You have to compile the kernel to support ATAPI / SCSI over IDE but that's about it I think

The x is the kernel reference - 1: /dev/hda1 is hd0,0
hda2 is hd0,1
hda7 is hd0,6
hdb1 is hd1,0
etc

Hope that helps

1)

Code: Select all

emerge development-sources

create the /usr/src/linux symlink

Code: Select all

cd /usr/src/linux
make menuconfig
make && make modules_install

3)
Add a line similar to the CD-ROM line (also with readonly set, only change the device and the mount point). The CD-writing ability is not important here.

4)
/dev/hda2 - hd0,1
/dev/hda3 - hd0,2
...

emerge gentoo-dev-kernel

2.) How can I read one variable ("IUSE_VIDEO_CARDS") from the file "/usr/portage/x11-base/xfree-drm" during the installation?

Not sure but I have "VIDEO_CARDS="rage128" in /etc/make.conf

3.) Chapter 8. - Code Listing 5

With a 2.6 kernel, not much, having cdr as a use flag is good, read the use descriptions, there is a link to them on the docs site, for others. Then emerge cdrecord

4.) Chapter 9 - Code Listing 5

If I have my root dir at /dev/hda1 - then it is hd0,0 !! What is the hd0,x - number for other /dev/hda's - for example for /dev/hda7 ??

sorry i don't do grub

about question 2:

see Chapter 7: - 7.e "Installing Separate Kernel Modules" and then I want to install the xfree-drm

about the cd-writer:

Whats the completely command line?

the kernel:

What is the exactly 2.6 - kernel version? 2.6.3?

[michaelb]

The section in the install handbook points out the differences between compiling a 2.4 series kernel and a 2.6 series kernel. If you want the 2.6 kernel, the only thing you need to know that is not expressly spelled out in the install handbook is what to emerge. I use gentoo-dev-sources, which gives you a 2.6 kernel with the gentoo patch set. The current exact version is

Code: Select all

 # emerge -pv gentoo-dev-sources

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild   R   ] sys-kernel/gentoo-dev-sources-2.6.3-r1  -build  0 kB 

Total size of downloads: 0 kB

For the issue with your CD burner, you just need to add a second line to fstab, which will point to the second drive. fstab does not care if it's a writer or a regular CDRom, so

Code: Select all

/dev/cdroms/cdrom0    /mnt/cdrom    auto      noauto,user    0 0
/dev/cdroms/cdrom1    /mnt/cdburner    auto      noauto,user    0 0

Of course, you will have to create the mount point for it to mount on

Code: Select all

# mkdir /mnt/cdburner

HTH,

To install the vanilla 2.6 sources, use emerge development-sources. To install the 2.6 sources with Gentoo patches, use emerge gentoo-dev-sources. Note that none of these kernel sources are available if you want to perform a networkless installation.

In this case you will have to download the vanilla-sources-2.4.24 as mentioned in the guide and, once completely installed, install the new kernel sources.

2.) How can I read one variable ("IUSE_VIDEO_CARDS") from the file "/usr/portage/x11-base/xfree-drm" during the installation?

Use a pager (such as less) to view the contents of an ebuild. For instance, less /usr/portage/x11-base/xfree-drm/xfree-drm-4.3.0-r2.ebuild. You can also use grep: grep IUSE_VIDEO_CARDS /usr/portage/x11-base/xfree-drm/xfree-drm-4.3.0-r2.ebuild.

3.) Chapter 8. - Code Listing 5

What must I add, if I want to "install" my cd-burner/writer (dont know if this is the correct english term ) next to my cd-rom-drive ?

Nothing in particular if you are going to use a 2.6 kernel anyway (as you don't have to setup IDE-SCSI emulation anymore). Just a line like the /dev/cdrom example.

4.) Chapter 9 - Code Listing 5

If I have my root dir at /dev/hda1 - then it is hd0,0 !! What is the hd0,x - number for other /dev/hda's - for example for /dev/hda7 ??

hda7 will probably turn into (hd0,6).
