 |
|
1. can i copy text from install console and paste in 'links' to this forum? accessing forum thru 'links' i've googled and tried some things but not working
2. what is difference between livecd ~# and livecd /#, does it make a difference issuing commands from one or the other?
3. choosing kernel
ls -l /usr/src/linux gave me 'linux-gentoo-2.6.29-gentoo-r5'
followed instructions for manually configuring kernel, compiled, then
'cp arch/x86_64/boot/bzImage /boot/linux-gentoo-2.6.29-gentoo-r5'
seems ok. on to configuring modules
'find /lib/modules/linux-2.6.29-gentoo-r5/ -type f -iname '*.o' -or -iname '*.ko' | less'
this said no such file or directory.
cd'd to /lib, 'ls modules' and it showed '2.6.29-gentoo-r5'
i tried 'find /lib/modules/2.6.29-gentoo-r5/ -type f -iname '*.o' -or -iname '*.ko' | less'
no modules shown. just '>_' i am in less right? should be able to exit by 'q enter'? or ':q enter" i can not exit.

First of all, welcome to linux! Don't get scared off... you'll get used to it in a short time.

Just so you know, the prompt is not the same across all linux distributions, and you can even change it for now. However, the default gentoo set up is what you have, and it's what most like.
"livecd" is your host name, or the name of the computer you're on. The livecd sets this to "livecd" - this will be different once you install on your machine (unless you like the name  ). the "#"at the end indicates that you are the root user (you have full power over the system - you are not a normal user). A normal user's prompt will display "$" here. The bit in between, the part that changes, is your current directory. The root prompt only displays the highest-up directory (so if you're in /usr/src, it will display "src"). The "/" indicates you are in the root of your filesystem (everything is mounted above there). The "~" means your home folder. "~" means your home, and ~user means user's home (you can use the tilde with cd and ls too. | Quote: |

exit that prompt with ctrl-c or so.
from /usr/src/linux, run "make modules_install".
Have fun!

if you're on the livecd, no, and it may or may not come with it there (but disabled) look in /etc/init.d (and make sure you do this in the livecd terminal, not the chroot.

If you plan on using gnome as your default desktop, then yes. You will need to emerge gnome, but only much later.
For now just continue following the handbook. You seem to be doing great.  |

Exit the chrooted environment and unmount all mounted partitions. Then type in that one magical command you have been waiting for: reboot - I expected a 
instead i have this
booting gentoo linux
root (hd0,0)
filesystem type is ext2fs.partion type 0x83
kernel /boot/kernel-2.6.29-gentoo-r5 root=/devram0 real_root=/dev/sda3
error 15: file not found
press any key to continue....
from handbook- and in grub conf file,
title Gentoo Linux 2.6.24-r5
# Partition where the kernel image (or operating system) is located
root (hd0,0)
kernel /boot/kernel-2.6.24-gentoo-r5 root=/dev/sda3
i edited kernel number to my kernel, 2.6.29-r5, was this right?
i don't know if a boot cd would help. i'm sure it would not help me as i'm running win xp/ vmware, trying to make .vmdk file

You did manual kernel configuration, right? And remembered to locate bzImage that was created ,and copied it to /boot?
line in grub.conf should be:
| Code: | | kernel /boot/exactly the same name as your kernel image name is |

make sure to also fix root= - real_root is only necesary for genkernel (and if you made an initrd, but I guarantee that you didn't)... you didn't use genkernel, right?

when copying bzImage to boot i write 'bzImage' or does it need to be edited?

i may have mistakenly used 'root= - real_root' from genkernel instructions |

When you copy your image for example "cp /usr/src/linux/arch/x86/boot/bzImage /boot/bzImage" it doesn't matter what name you give your kernel, just remember to write it down to your grub.conf exactly the same(remember Capitals do make difference!) |

Example process of kernel configuration and copying:
1. cd /usr/src/linux && make menuconfig
2. make && make modules_install
3. At the end of compilation you see destination where bzImage is stored, (you can also do "slocate -u && slocate bzImage" to find it)
4. then you do "cp /path/to/your/bzImage /boot/whatevernameyouwanttogiveyourkernel"
5 cd /boot
6. ls -la, make sure your image is there
7 nano /boot/grub/grub.conf
8. edit your grub.conf

viewing available modules shows me this
kernel/configs.ko
drivers/media/video/gspca/gspca_main.ko
drivers/hid/hid_dummy.ko
drivers/scsi/scsi_wait_scan.ko
arch/x86/kernel/test_nx.ko
is there anything i can or should add to my '/etc/modules.autoload.d/kernel-2.6'
also, Code Listing 3.2: Opening /etc/rc.conf, , says DISPLAYMANAGER has moved to /etc/conf.d/xdm.
this was a 'new file' so i added 'DISPLAYMANAGER="gdm" '
hope this is ok.
i'm continuing install but won't reboot till sure everything is ok |

Did you enable SCSI support in your kernel? | Code: | < > ATA/ATAPI/MFM/RLL support
SCSI device support -->
<*> SCSI disk support
<*> Serial ATA (prod) and Parallel ATA (experimental) drivers -->
<*> <YOUR CONTROLLER TYPE> SATA support |
I wish there was a sticky thread for this recurring problem.  |

Something like this ("ro" at the end of the kernel line for jfs) but you don't really need it because the kernel boots your partition "ro" at first by default.

i've had gentoo up a couple times and broke it. broke it trying to get multimedia players to play avi files.
so installing again. i am paying more attention to use flags. i want a smooth install for xorg-server, gnome and vlc.
emerge -pv xorg-server gives, for example, USE="(-selinux)", why is it in parantheses?
i'm thinking of leaving make.conf as is and Declaring USE flags for individual packages.
i have looked at /usr/portage/profiles/base/make.defaults. i have selected Desktop profile, how do i view this profile? |

for me, adding "doscsi" to kernel options line did the trick..
| Quote: | | USE flags in (parenthesis) are forced, masked or removed by your profile, -dash are disabled flags, asterisks* indicate that a flag has changed since the package was last emerged while percentage% indicate that it has been newly added or removed as an option. |

i guess /usr/portage/profiles/default/linux/x86/2008.0/desktop/make.defaults (of course replace x86 with whatever platform you're on)
