arc3:~$ uptime

Everything's easy on a live, running system.

Oh, *that*?  In that case, you don't give a flying leap how long ago you
rebooted.  What you care about is the *exact running kernel version*.

arc3:~$ uname -v
#1 SMP Debian 3.16.39-1 (2016-12-30)

Then you compare 3.16.39-1 against the changelog.Debian.gz to see if it's
got the bug fixes you want.
