Public bug reported:
So unity8's launcher is going to start grabbing application/icon info
from UAL. Which is great.
However, consider these two scenarios:
1) Application A in launcher is uninstalled -- icon should disappear from
launcher.
2) Application B in launcher is updated and has a new icon -- icon should
update in launcher.
The current way unity8 listens for this is not great. We install a
session upstart job that listens to /usr/share/applications/*.desktop
and /home/phablet/.local/share/applications/*.desktop (notice hardcoded
phablet) and tells the launcher to refresh if anything changes.
Obviously this doesn't work for snaps. And is not super elegant. If
UAL could tell us that something changed (it could even be at the
granularity of "anything in the entire registry"), we could drop our
filewatcher job and handle situations #1 and #2 above better.
