[lfs-support] Exotic lfs compiling question
Heya all. Need some help. I have an old lfs installation which is in production use, for the past 5-6 years. I guess it's version 6.3 or something since it has kernel 2.6 on it. It is time to install a new version on it. But there are the following problems: 1.) Since it is in production it can't be offline longer than 3 hrs. So the new lfs has to be compiled while the old dist is still running and then when everything is finished just copied to root. 2.) The compilation has to be done on this machine. 3.) There can't be installed any other distribution (Ubuntu, RedHat,...) or any virtual machine. 4.) Obviously I can't compile lfs 7.4 with 6.3. So here is what I need. Which lfs version can I use as a jump pad. For instance can I compile 7.0 with 6.3 and then compile 7.4 with 7.0? I can use chroot on this machine. And it isn't a problem even if I have to do a three step compile (i.e. 6.3 - 7.0 - 7.1 - 7.4) So the question is can I compile some version of lfs which can be compiled on 6.3 and can compile 7.4 and can I do both or more compilations in chroot? THX in advance... Daniel -- http://linuxfromscratch.org/mailman/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/lfs/faq.html Unsubscribe: See the above information page

You can build LFS 7.4 (probably go with 7.5-rc1) from 6.3 with some minor tweaks. If your running kernel is up to at least 2.6.32 then default glibc configure options will work. If it is less than 2.6.32, then you'll need to adjust the glibc configure commands otherwise you will get FATAL: Kernel too old once you start using the new glibc in tools. Other than upgrading tar if not already so it'll us xz, and add xz to your system. 6.3 still meets the host system requirements outside of the running kernel update, tar update, and addition of xz. Gawk 4.1 upgrade isn't necessary as 3.15 even still works when building tools. However, you may want to anyway. Without upgrading the kernel headers you won't be able to upgrade your host's e2fsprogs to 1.42 and upgrade udev. You'll also need to upgrade make. I updated the lfs livecd a while back to build 7.x versions. you can look at my notes to see what I upgraded. If I didn't upgrade something to the newest version and it is stuck at an old version, namely udev and e2fsprogs, it is cause of the old kernel headers installed. http://clfs.org/~kb0iic/livecdupd/ I haven't tested the updated livecd with 7.5, but if host system requirements didn't change since 7.4, it'll work. You can bring your 6.3 up to date rather easily without much effort.

Don't top post.
Ecit /etc/sysconfig/rc.site and uncomment:
#IPROMPT=yes # Whether to display the interactive boot promp
#itime=3# The ammount of time (in seconds) to display the prompt
When you boot, it asks if you want to do an interactive prompt. Say
yes. You can then step through the boot scripts one at a time.
Edit /etc/rc.d/init.d/network and add
'echo $interface' right below the line
interface=${file##*/ifconfig.}
Then lets see what you get.

A small info on the server that I wan't to update. It's a Database server with MySQL 5.1.45, PostgreSQL 9.1.8, and the most problematic one is ArcSDE 10.1 DB connector which has some dependant X11 libraries. I don't know how it will react with upgraded kernel headers, Gawk, e2fs and especially udev. And for udev I also dread if the bonding of 4 network cards and the Adaptec RAID adapter will have problems. As I said I can turn off the machine only for 3 hrs and that is the complete fallout that it can have for this year. So I would go with less if I can. The DB backup will take me 20mins, the filesystem adaptation another 15min, and then I have 2:25hrs for problems. I would like to have no problems. :) This machine has been offline for 2hrs in summary for the past 4yrs. I even thought to put another machine in its place until I finish the compilation but unfortunatly I don't have another machine which could cope with the load. I updated the lfs livecd a while back to build 7.x versions. you can look at my notes to see what I upgraded.
