Hi Michael,
I remmember that there is an issue if you have different kernel versions
and use dracut.
From my notes when I came across this:
* The package dracut needs a patch for /usr/lib/dracut/dracut-functions.sh,
see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=685004, otherwise
all modules are missing if the kernel version in the nfsroot and on
mucha differ.
* Patch is applied by an nfsroot-hook script named
/etc/fai/nfsroot-hooks/15-dracut-patch.
See below for the file contents. It runs when the nfsroot is being
created.
Also, I did some clean-up in /etc/fai/NFSROOT by commenting out
conflicting lines.
I hope the info helps,
w.w.

Hi,
I am trying to set up fai (4.0.5) for Ubuntu 12.04, first of all trying to
build the nfsroot... but I'm kind of stuck here. Could someone give me a hint
here? I'm trying to build the nfsroot on a virtual machine, also running
Ubuntu12.04.
If you need further information, like my NFSROOT or nfsroot.conf or
sources.list or anything else, let me know. I copied what I think may be
valuable information from the fai-make-nfsroot.log below.
Kind regards,
Michael
The fai-make-nfsroot.log looks ok for the first 1400 lines, but then:
1403 The following packages have unmet dependencies:
1404 console-tools : Conflicts: console-utilities which is a virtual
package.
1405 Conflicts: open which is a virtual package.
1406 kbd : Conflicts: console-utilities which is a virtual package.
1407 Conflicts: open which is a virtual package.
1408 The following actions will resolve these dependencies:
1409
1410 Remove the following packages:
1411 1) console-setup
1412 2) kbd
1413 3) ubuntu-minimal
and then, another 300 lines later:
1708 dracut: Generating /boot/initramfs-3.2.0-37-generic-pae.img^M
1709 E: Directories consolefonts, consoletrans, keymaps, unimaps not found.
Please inform us about the issue including your OS name and version.^M
1710 E: FATAL: Could not load /lib/modules/3.2.0-37-generic-pae/modules.dep:
No such file or directory^M
the last line is repeated some 20 times then, occasionally find jumps in and
reports:
1717 find: `/lib/modules/3.2.0-37-generic-pae/': No such file or directory^M
which is strange, because the directory (as well as the modules.dep file, for
that matter) exists (on the host - not inside the nfsroot!)
At the end, I get
