Re: [gentoo-user] Transferring an existing install to new disk
I did it last week. in some place untar che last stage3-xxx mount --bind proc, dev, usr/portage, passwd, group ecc copy inside current make.conf, make.profile chroot inside the new stage. when finish i make a big tar of everyone in the new chroot. reboot with live cd, move all my old system in /old, untar the new system on the rootfs. if something is missing in the new system , you have the original file of configuration in /old P.S. sometime i make something like stage4 from livecd and i store it in a USB HD. If something is going wrong, in 20 min i can restore all my system.

I can't recall why I switched but I did. Grub is so much easier than Lilo. I have no regrets with switching and would only use Lilo if it was all that was available. The biggest thing to learn is the way the drives are listed. It uses (hd0,0) and such. It's really not that hard once you get how it does it. Also, it is real easy to switch to a older kernel at the grub boot screen. Just edit the boot line and let it rip. You can also edit other options for the boot line but changing kernels is the big one for me. It's a thought. Dale :-) :-)

I use LILO. My lilo.conf traces its ancestry back to my original Linux installation, SuSE 5.3. Why? Because learning grub would take time. Maybe not very much time, but it would take some. By contrast, although learning LILO took a very great deal of time, that time is already spent, and can never more be got back. Putting an extra entry into lilo.conf and regenerating the boot loader now takes, at most, a few minutes. But if the motivation of your question is simplifying Gentoo by leaving out LILO, that wouldn't bother me at all. While I've still got a Debian on my PC, I can use it to lie low, and when I need to learn grub, no big deal. In fact, by the time I get to learn grub, it will, in its turn, probably have been superseded by something else. :-) > Regards > Dirk -- Alan Mackenzie (Nuremberg, Germany).

I think the symlinks shouldn't get affected by the tar+ssh transfer. There is some tar option that preserves stuff. Take a look at man tar. I use tar to do regular backups of my complete system and restored it at least one time without problems. When I am back home I can look up the command I use. -- Regards, Daniel

Harry was asking about going between two machines. I did something similar recently ((http://blog.garrysmith.net/?p=62#more-62) and used the following command to pass the output from tar directly to the destination machine over SSH: tar -cvzpf - ./bin ./boot ./dev ./etc ./lib ./lost+found ./media ./mnt ./opt ./proc ./root ./sbin ./sys ./usr ./var | ssh -p8889 [EMAIL PROTECTED] “cd /mnt/gentoo; tar -xzpf -” Unfortunately the symbolic links all came out as 0 byte files (not sym links), so in the end I fell back on rsync (over SSH) which did the job. How do you normally preserve symlinks using tar piped over SSH? An example of the rsync command I used was: rsync -avpe "ssh -p 8889" /home [EMAIL PROTECTED]:/mnt/gentoo The next time that I do this, I will just use rsync straight away and not use tar. The Gentoo Live CD has rsync (the Gentoo minimal install doesn't), so you should use the former (I booted both machines (one of them within VMWare fusion) from live the CD in order to do the copy. cheers Garry

[gentoo-user] Transferring an existing install to new disk
I should know how to do this but so many changes have happened recently and I haven't done anything like this for a very long time. My desktop version of gentoo is pretty far out of date. And I think there have been enough changes that I don't even want to try to get it cleaned up. Rather, I'd like to build up a newly installed gentoo to the point where it has all the stuff I want. But do it inside a vmware virtual machine. I'm trying to keep my working desktop in place until such time as the vmware gentoo setup is ready Once that install is up to speed with all my preferred apps in place. And any kinks worked out...
