It looks like we have a small but interesting set of sysctl users.

The list of files below is a composite from a number of systems I have
access to, and the reply I have gotten so far. I'm still hoping to hear
from other people so I can add some other users of sysctl to my list.

I'm still investigating to see how all of these pieces are using
sysctl, and how much they care:
- radvd seems to be an upstanding user.
- libsensors seems to be using sysctls so we have no responsibility to
maintain the ABI there.
- libpthread uses sysctl but it doesn't much care.
- module_upgrade seems to be setting the printk verbosity?

The nvidia-installer sounds like a scary piece of code.

I'm puzzled why the majority of the users seem to be concentrated
in system configuration software and installers.


Compiling the results I have so far (Some of these are from older distros):
