Control: affects -1 xen-tools

[I initially sent this to the wrong clone (#764596) of this bug
report, so I'm now hopefully resending it to the right bug report.]

Same counts for Sid Xen DomU bootstrapped via xen-tools (at least with
the git version, both with the modification mentioned below as well as
with an unmodified git checkout):

$ xen-create-image --dist sid --hostname domu1 --force --lvm vg0 --dhcp 
--verbose --pygrub --noaccounts --boot; xl console domu1
[...]
Begin: Checking root file system ... fsck from util-linux 2.25.2
fsck: error 2 (No such file or directory) while executing fsck.ext3 for 
/dev/xvda2
fsck exited with status code 8
done.
Failure: An automatic file system check (fsck) of the root filesystem failed.
A manual fsck must be performed, then the system restarted.
The fsck should be performed in maintenance mode with the
root filesystem mounted in read-only mode.
Warning: The root filesystem is currently mounted in read-only mode.
A maintenance shell will now be started.
After performing system maintenance, press CONTROL-D
to terminate the maintenance shell and restart the system.

I expected that this would count for xen-tools as well and tried to
fix it by explicitly installing e2fsprogs before initramfs-tools and
the kernel. But the above still happens despite I used this code to
install e2fsprogs, initramfs-tools and kernel:

        installDebianPackage ${prefix} e2fsprogs
        installDebianPackage ${prefix} initramfs-tools
        installDebianPackage ${prefix} $KERNEL_PKG

So I doubt that this can be fixed by reordering the package
installations. (Besides: the log said "e2fsprogs is already the newest
version.", so it didn't change anything.)

The following fsck binary is in the initrd:

# lsinitramfs -l /mnt/tmp//boot/initrd.img-3.16-3-amd64  | fgrep fsck
-rwxr-xr-x   1 root     root        35664 Oct 24 19:02 sbin/fsck
