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 between the stock Debian initrd from the kernel package and
the FAI initrd. (I am just talking about the initrd, not about the
kernel as such.)
1. Trying this with the stock Debian initrd:
Begin: Mounting root filesystem ... /init: .: line 171: can't open
/scripts/live
Kernel panic - not syncing: Attempted to kill init!
2. Using the FAI initrd copied from the nfsroot instead:
Begin: Running /scripts/live-premount ... done.
IP-Config: eth0 hardware address xx:xx:xx:xx:xx:xx mtu 1500 DHCP RARP
So this is trying to do DHCP despite a ip= kernel command line with a
static config.
Interesting enough, nothing ever comes after this DHCP line. No timeout,
no error message, nohting. But AFAIK there is no DHCP available in the
data center, so trying to configure the network interface via DHCP is
pretty pointless here.
So I might want to make some experiments with modifying the scripts
inside the initrd.
The question may be OT on this list, but has the ip=... kernel parameter
any meaning when using an initrd?
Regards,
Torsten

Yep, FAI is using a stock Debian kernel, which includes some
hooks/plugins for initramfs. We use the live-initramfs packages that
add some script into the initrd.

You can find the "FAI initrd" inside the nfsroot. /srv/fai/nfsroot/...../boot

That's not true nowadays.

That's part of live-initramfs, but you do not need to care about this.
FAI is runnung from /. AFAIK /live is only used during boot, before a
pivot_root is done.
