Object: to get a custom fact that lets me know the last time a Ubuntu system
had run 'upgrade' (ie apt-get upgrade or aptitude [safe-|full-]upgrade)
One-liner: (will probably still need some adaptation but so far, I am doing)
tac /var/log/apt/history.log | \
awk '{if (substr($0,1,8)=="Upgrade:") { getline; print }}' \
| head -n 1
which will return something like: 'Start-Date: 2011-11-21 23:51:47' which I
can cut the date out of and store as a custom fact - ie... last_upgrade:
The problem is that the logs rotate and now this may be in
/var/log/apt/history.2.gz or possibly get rotated out of existence altogether
and while I can loop and search for the last time an upgrade was run, I may not
actually be able to get that date and would want the last_upgrade to persist.
Now I could conceivably store this value in say /var/lib/puppet/last_upgrade so
I always have a fallback, I'm wondering if there isn't a better way.
