what writes to /root/.cache/mesa ?

Dear All,

I have several CentOS 7 machines (but not all of them) on which I have
noticed that something gets written to

/root/.cache/mesa

every so often (once every several days). It is my understanding that
mesa is related to GUI (X11), but on these machines (on neither of my
machines, actually) root never logs in to GUI X11. I may have remote
root logins with Xforwarding though. Hence my puzzle: what is that that
writes to /root/.cache/mesa? Some, but not all of occasions seem to
happen upon machine [re]boots.

Thanks.
Valeri

PS This gives me dejavu. A while ago when people started demanding to
have google chrome browser installed on their workstations I had hard
time to get rid of google's cron jobs that were writing where only root
should - without explicit permission to do so. Dough. Somebody's
software thinks it is smarter than everyone who uses it... "Machine
learning" all the way ;-)

Since I work at a university that uses Google Apps, we're asked to
provide Google Chrome for all our users, but since the package is not
very enterprise ready, I have to make several adjustments.

One thing I do is put an 'exit 0' in /etc/default/google-chrome. This
effectively stops most of the evil that the RPM does in its
postscripts. (As a reminder, this is what the latest RPM does,
<a href="https://paste.fedoraproject.org/paste/MS~7Fkr5AWYo7SAWAl8t6A" title="https://paste.fedoraproject.org/paste/MS~7Fkr5AWYo7SAWAl8t6A">https://paste.fedoraproject.org/paste/MS~7Fkr5AWYo7SAWAl8t6A</a> )

I also manage private repos (with pulp) of the Google Chrome repos, in
case I need to go back to a previous version, so having it overwrite
my repositories is actually damaging.

I also disable 'at' and the atd service on our workstations, and this
RPM turns atd back on and schedules an at job to run the
/etc/cron.daily/google-chrome script.

It's an absurd RPM and Google should be ashamed of it.

Thanks for your input, very instructive!

Google is not ashamed of what it is doing. As one clever man said over
decade ago: you don't need to recruit spies anymore, just roll out
"free" services. And we all know, these "intelligence" agencies were
never ashamed of whatever they have done.

But as another clever man said: the people do deserve the government
they have.
