Public bug reported:
snappy in 16.04 used to compare /usr/share/snappy/security-policy-
version and /var/lib/snappy/security-policy-version on boot to see if
the apparmor package changed and therefore if it needed to regenerate
all snap policy. This functionality was recently removed with nothing
added to replace it.
snapd must have a means to detect changes to the parser or the
abstractions which the snap may #include, otherwise we cannot deliver
parser and policy fixes from apparmor to installed snaps. It is fine to
use a different method than what we had before, but we need to have
something.
