The command in question was: rpm -Uvh --force *.rpm
where the RPMs were glibc and glibc-common.

Aren't you exaggerating a little?
There are a lot of commands I would feel perfectly safe giving remotely,
eg "sudo yum update" which I've said a couple of times a week
for the last 3 years without any disasters resulting.

The trouble with the command above is that I am not sure
if a change in glibc would affect a running kernel?
I suspect that it would not.

I don't know what a "downtime window" is in this context.
I'm either in the same place as the server, or I am not.

I'm not really in that kind of environment.
It isn't the end of the world if the machine goes down;
just a little annoying.
