 You're missing set root=(hd0,6) for in the LFS7 menu entry.

Yes thanks that boots the new system okay but leaves lfs6unbootable .  I.e no 
file found.  There must be some kind of syntax error here somewher.

Instead of global set root statement, define it in each menu entry like 
this:

menuentry LFS6, Linux 3.12.1-lfs-7.2 {
 set root=(hd0,7)
 linux /boot/lfskernel-3.12.1 root=/dev/sda7 ro

The set root instructions should be inside the brace:
menuentry LFS6, Linux 3.12.1-lfs-7.2 {
set root=(hd0,7)
linux /boot/lfskernel-3.12.1 root=/dev/sda7 ro
}

and same for the second one, replacing 7 with 6. Note that the root set by
set root does not need to be the same as the root= kernel parameter.

For example, you could have all the kernel files on the first partition and
have something like:
set root=(hd0,1)
linux /lfskernel-3.12.1 root=/dev/sda7 ro

(notice that /boot is suppressed in the last line). Then you could mount
/dev/sda1 on /boot with /etc/fstab.

Re: [lfs-support] LFS 7.4 - Chapter 8.4 - GRUB

 Don't optimize the bootloader. Grub doesn't need optimizations. No  
 bootloader needs optimization from gcc. You are dealing, also, with

 install strace and gdb and debug.
 
 I write this because grub, in the past has, segfaulted when using -O3  
 or -march set, even from before Grub 1.
 
 Even when using -O3 you can get a loading grub... message that  
 hangs.  Rebuild grub without optimizations and return with results.

Yup. Don't use optimizations with GRUB :) Turned them off and grub now
works from chroot.

Still have the init problem from initramfs but that's another story.

Thanks...

This type of problem is generally solved by having /boot on a separate 
partition.  It also gives the advantage of being able to access boot.cfg 
from any booted system without a separate mount.

[lfs-support] LFS and network aliases on ethernet ports

2013-12-22 Thread Geoff Swan 
Is it possible to add alias networks to an ethernet device in LFS-7.4?

I was used to the old method of having ifconfig-eth0:1, etc with the
alias network defined in this file, as for the ifconfig-eth0 file.
However the alias files do not appear to be recognised on boot. I don't
thing the /lib/services/ipv4-static script recognises the config files.

IP=205.158.179.178
GATEWAY=205.158.179.161

 GATEWAY=205.158.179.161
 PREFIX=27
 BROADCAST=205.158.179.191

For testing, make ONBOOT=no.  The GATEWAY needs to be commented out 
since it is not in the eth0:1 network.

You can then test using '/sbin/ifup eth0:1' or 'ifdown eth0:1'

BTW, You never said what messages you got, if any.  You should get some 
kind of message for either success or failure.

After getting it to work, change ONBOOT back to yes.
