 |
|
When I compile the gentoo-sources, after | Code: | | make && make modules_install |
I failed to run
It gives the error | Quote: | sh /usr/src/linux-2.6.29-gentoo-r5/arch/x86/boot/install.sh 2.6.29-gentoo-r5 arch/x86/boot/bzImage System.map "/boot"
Cannot find LILO |
But I'm using grub. Could you tell me what's happening please?

Try cleaning first with
and then
| Code: | | make && make modules_install |

there shouldn't be any need to run a 'make install'
if you follow the handbook, it tells you how to do everything by hand, step by step
| Code: |
make && make modules_install
|
then make sure /boot is mounted (you should have mounted it before you chrooted)
| Code: |
cp /usr/src/linux/arch/x86/boot/bzImage /boot/kernel-new
|
then edit /boot/grub/grub.conf to have
| Code: |
title Gentoo
root (hd0,0)
kernel /boot/kernel-new root=/dev/sda3
|
Replace 'sda3' with whatever is appropriate for your root partition
as well in some cases it wont be hd0,0, but something else
No need to do `make install` - the above is the correct procedure for building and deploying a new kernel in most gentoo installations
Once you've done that
| Code: |
emerge grub
grub-install --no-floppy /dev/sda
|
(replacing sda with whatever is appropriate)
If you're lost, consult the handbook, as all of the above is documented there  |

also should point out, you need to have populated /etc/mtab (as per the handbook) before doing grub-install
Mine is below, however it will look considerably different from yours, as I'm using LVM && dmcrypt, with only small partitions for root and boot
| Code: |
/dev/sda2 / reiserfs rw,noatime 0 0
proc /proc proc rw,nosuid,nodev,noexec 0 0
sysfs /sys sysfs rw,nosuid,nodev,noexec 0 0
udev /dev tmpfs rw,nosuid,size=10240k,mode=755 0 0
devpts /dev/pts devpts rw,nosuid,noexec,gid=5,mode=620 0 0
/dev/mapper/crypt-usr /usr reiserfs rw,noatime 0 0
/dev/mapper/crypt-home /home xfs rw,noatime,logbufs=8 0 0
/dev/mapper/crypt-opt /opt xfs rw,noatime,logbufs=8 0 0
/dev/mapper/crypt-var /var reiserfs rw,noatime 0 0
/dev/mapper/crypt-tmp /tmp reiserfs rw,noatime 0 0
shm /dev/shm tmpfs rw,noexec,nosuid,nodev 0 0
usbfs /proc/bus/usb usbfs rw,noexec,nosuid,devmode=0664,devgid=85 0 0
binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,noexec,nosuid,nodev 0 0
nfsd /proc/fs/nfsd nfsd rw,noexec,nosuid,nodev 0 0
/dev/sda1 /boot ext2 rw,noatime 0 0
|
For most, your /etc/mtab should look something like
| Code: |
/dev/sda3 / reiserfs rw,noatime 0 0
proc /proc proc rw,nosuid,nodev,noexec 0 0
sysfs /sys sysfs rw,nosuid,nodev,noexec 0 0
udev /dev tmpfs rw,nosuid,size=10240k,mode=755 0 0
devpts /dev/pts devpts rw,nosuid,noexec,gid=5,mode=620 0 0
shm /dev/shm tmpfs rw,noexec,nosuid,nodev 0 0
usbfs /proc/bus/usb usbfs rw,noexec,nosuid,devmode=0664,devgid=85 0 0
binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,noexec,nosuid,nodev 0 0
/dev/sda1 /boot ext2 rw,noatime 0 0
|
if you use my examples, adjust sda1/sda3 as is appropriate for your installation |

Have you updated sys-apps/debianutils recently ?
It is possible that /sbin/installkernel (used by the kernel's "make install") no longer supports old versions of grub.
I currently use grub2, and "make install" continues to be my preferred way to install a new kernel. |

Try it yourself sometime and see. Running 'make install' automatically manages symlinks under /boot: vmlinuz and vmlinuz.old (among other things). If you setup grub.conf to use these symlinks, you never have to touch grub.conf again.
Here are my grub stanzas, for example:
| Code: | title Gentoo Linux
root (hd0,0)
kernel /boot/vmlinuz root=/dev/sda3 vga=0x317 video=vesafb:mtrr:3,ywrap,vtotal:32
title Gentoo Linux (backup kernel)
root (hd0,0)
kernel /boot/vmlinuz.old root=/dev/sda3 vga=0x317 video=vesafb:mtrr:3,ywrap,vtotal:32 |

If you look at the install.sh script in the above quote, you'll see that Simon doesn't have /sbin/installkernel installed. It's part of "debian-utils." Despite the "Cannot ...." message, the kernel and System.map files should have been installed in /boot, since the script just does cp/cat if it can't find "installkernel.".

I don't use this make install stuff, but just one thought: /boot is mounted properly when you make install? |

The make install is convenient as far as I know. And I have been using it for quite a long time. It generates automatically the symbolic links in /boot.
I installed debainutils, it removed the error complaining "cannot find lilo", but the symbolic links are still not generated. I tried to install grub2, but failed when emerge.
The boot is mounted. |

It turns out the /sbin/installkernel is a bit too smart for its own good. It won't create the symbolic links unless one already exists. Here's the comment: | Code: | # The presence of "$dir/$1" is unusual in modern intallations, and
# the results are mostly unused. So only recreate them if they
# already existed.
|
You should be able to fool it by manually creating a set of links to the currently running kernel before running "make install." You'd need something like this to be present in /boot:
| Code: | vmlinuz -> vmlinuz-2.6.30-gentoo-r3
config -> config-2.6.30-gentoo-r3
System.map -> System.map-2.6.30-gentoo-r3 |
Pretty damn ugly that you need to go through that, but I too find "make install" to be very convenient. I'm guessing that earlier versions of debian-utils didn't have that stupid (IMHO) check on the existence of those links.

| Yes, after create the initial symbolic links, the make install works fully (copy the kernel to /boot, and create appropriate symbolic links). Thank you all for the help. |

The problem is coming from the use flag "installkernel" unset on debianutils.
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] sys-apps/debianutils-4.11.1::gentoo USE="installkernel* -static" 0 KiB
[ebuild N ] sys-kernel/installkernel-gentoo-2::gentoo
when set, all will be ok. |

Thank you! I unset it ages ago and wondered why the hell the kernel isn't installed properly. Well, mistery solved! |
