Public bug reported:
On debootstrapping fresh environment (amd64 in my case) udevd starts up
and prevents from unmounting the image/partition mounted on the target.

Testsuite: autopkgtest
# Steps to reproduce:
* create an image/partition of sufficient size (1G will suffice for a simple
test) and format with some FS
* debootstrap like: debootstrap --arch=amd64 --variant=minbase
--include=language-pack-en,wget,curl,language-pack-en-base trusty
/target/0481fbd0/root http://bg.archive.ubuntu.com/ubuntu
* wait for the debootstrap to finish
* try to unmount --> fail
# Expected outcome:
* be able to cleanly unmount the image/partition
* udev not restarted inside the debootstrap env
The problem lies in the postinst script which does
invoke-rc.d udev restart.
During debootstrapping we have no ability to configure the init scripts policy
layer to prevent execution. Therefore the udev postinst should check if it is
in a debootstrap environment and if so not start/restart. Other actions like
updating HWDB and seting startup scripts are fine and acceptable.
This bug is analogous to Debian #520742, and Ubuntu #1260707.
The solution in debian is to check for debootstrap env and not
start/restart.
The issue in Ubuntu seems to have been introduced in 202-0ubuntu6 ( -
Add debian/udev.postinst for restarting udev and rebuilding initramfs.)
