Sorry for the belated reply, but having recently switched from another distro
this bothered me as well. The typical advice to use dpkg/apt-query/aptitude
only tells half the story - those tools only know which kernel is installed,
not what is running. I finally found what I was looking for in /proc/version.
$ cat /proc/version
Linux version 2.6.32-5-amd64 (Debian 2.6.32-38) (b...@decadent.org.uk) (gcc
version 4.3.5 (Debian 4.3.5-4) ) #1 SMP Mon Oct 3 03:59:20 UTC 2011
Based on that I wrote a shell script to tell me if a machine needs a reboot,
the heart of which is:
RUNNINGKERNEL=`awk '{print $5}' /proc/version | tr -d ')'`
INSTALLEDKERNEL=`dpkg-query --show --showformat='${Version}\n' linux-base`
if [ "$INSTALLEDKERNEL" != "$RUNNINGKERNEL" ]; then
echo "Running kernel (version $RUNNINGKERNEL) not the same as latest
installed kernel (version $INSTALLEDKERNEL)."
fi
At least this works on amd64 Squeeze.
