Andreas Florath 43bc352c59 debootstrap: Call update-initramfs explicitly
Many elements install additional distribution packages.
In addition the user can provide a set of packages to be installed
via the '-p' switch.
Some of them influence the boot process and therefore the initramfs
needs to be updated. Because the package manager during the image
creation process is configured not to run package scripts, this needs
to be done explicitly.

This issue was found during development and debugging of the
block-device LVM plugin: Even when the e.g. the lvm2 package
was installed in the image, it was missing in the initramfs
because of the missing update.

update-initramfs -u
# Please note that the 'dracut-regenerate' element does a similar job.
# Nevertheless the update-initramfs / mkinitramfs are (currently) the
# standard way for Debian / Ubuntu.
# Also the 'dracut-regenerate' element can currently (Sep 2017) not
# be used with Ubuntu, because of some problems, e.g. it clashes with
# the ubuntu-minimal distribution package (not the DIB element with
# the same name).
