Bug Description
I'm trying to boot a virtual ubuntu (Xen domU) from an nfsroot (to install the OS using fai), but I get a kernel panic when initramfs tries to mount the root filesystem. Since fai uses live-boot I suspected aufs, and this is what I found:
The kernel config says that aufs should be compiled as a module, but the ko-file is missing. The generic kernel has the same configuration, and that package (which I cannot use for a paravirtualized installation) includes aufs.ko.
I have noticed this problem in two different kernel packages (both x86):
linux-image-
linux-image-
A search for aufs.ko on packages.ubuntu.com confirms that the file only exists in the generic, generic-pae and server flavors.
This typescript illustrates the problem (I cannot include the mandatory lspci output since the commands below are run chrooted to the nfsroot on the fai installation server):
$ chroot /srv/fai/
$ grep AUFS_FS /boot/config-
CONFIG_AUFS_FS=m
$ grep -i aufs /boot/config-
$ grep -i aufs /boot/config-
$ diff -s /tmp/generic /tmp/virtual
Files /tmp/generic and /tmp/virtual are identical
$ dpkg -L linux-image-
/lib/modules/
/lib/modules/
$ dpkg -L linux-image-
/lib/modules/
