Em, so shortly after I posted this bug, I had the same issue in wheezy, and since you couldn't reproduce the issue and I did not remember facing that same issue before on Debian 7, something rang a bell.
It looks like the problem is due to a kernel change by the host on which my Debian VM runs. Here's the 'uname -a' for a Linode wheezy VM: Linux li652-239 3.14.4-x86_64-linode40 #1 SMP Tue May 13 12:25:05 EDT 2014 x86_64 GNU/Linux And the one with the stock Debian kernel on the same VM: (As reported after following: https://library.linode.com/custom-instances/pv-grub-howto) Linux (none) 3.2.0-4-amd64 #1 SMP Debian 3.2.57-3+deb7u1 x86_64 GNU/Linux Here is the output of 'checkrestart -v' with the Linode kernel: Found 1 processes using old versions of upgraded files (1 distinct program) Process /usr/sbin/mysqld (PID: 7268) List of deleted files in use: /[aio] ((Etienne: This line is repeated 204 times)) Running:['dpkg-query', '--search', '/usr/sbin/mysqld'] Reading line: mysql-server-core-5.5: /usr/sbin/mysqld (1 distinct packages) These processes do not seem to have an associated init script to restart them: mysql-server-core-5.5: 7268 /usr/sbin/mysqld And the output of 'checkrestart -v' with the stock kernel on the same VM: Found 0 processes using old versions of upgraded files So it looks like it's a problem with the Linode kernel, namely 3.14.4-x86_64-linode40. However, although only partially related, Ubuntu 14.04 LTS throws the exact same message with MySQL 5.5 with either Linode's kernel, the stock kernel, or a VMware-based VM, so I'm thinking this may be an issue with the version of the kernel, which is even stranger, because you tested on sid, which is 3.14 and didn't get the issue, Linode is 3.14, and both other Ubuntu builds I tested are 3.13.
