Hi Jean! i think the goal here is to take any machine from a provider that you do not control via dhcp or pxe and use fai anyway to reinstall it from scratch. I couldn't have explained it better. If you knwo how i am interested :) Well, as I already mentioned, some ideas (which have worked

Hi Henning! But the basic-installed systems wasn't installed using FAI. That's not necessary for softupdates. No, but I *want* it to have been installed by FAI. The whole point here is to have identical (well, at least similar) installations of Debian across servers rented from different

Hi again! propose, but also kexec seems not to be what you need - kexec just changes the kernel, but keeps all processes and stuff runnning, No, it doesn't. It would be wonderful if a tool would exist which just changes the kernel on a running system. Starting a new kernel with kexec is

Hi! Quick update on this subject: I decided to spend the money and have a technician in the DC connect an IP based KVM remote console temporarily, so if the book process hangs, I can see now *why* it hangs. In contrast to what has been said here before, there seems to be a difference

Hi Thomas! Have a look at /srv/fai/nfsroot/live/filesystem.dir/usr/share/man/man7/live-initramfs.7.gz It describes all parameters of the live scripts. Where would I have to change them and what command will re-built my initrd image afterwards with the changed parameters? I think I don't

Hi all! Did anyone ever try to use kexec to start a FAI installation? My question is related to: http://faiwiki.informatik.uni-koeln.de/index.php/Using_FAI_to_install_a_root_Server In other words: We get servers which have some random Linux image on them. We don't have physical access to

I might not fully understand your case, but on an already basic-installed system, I'd simply run fai softupdate. Wasn't kexec some system for changing the running kernel without reboot? Henning i think the goal here is to take any machine from a provider that you do not control via dhcp
