Slow inventory on RHEL8 / CentOS 8 : `ssh-keyscan -T 1 127.0.0.1`
Description
It has been found out that « Rudder agent inventory » takes 3 minutes to run on a customer's RHEL8 nodes.
Running the inventory with -v shows that it apparently waits 3 minutes waiting for `ssh-keyscan -T 1 127.0.0.1` to complete.
The issue has been reproduced on a Centos Stream 8 node, where the inventory halts for 30 seconds at the same step.
With the same agent version, the inventory doesn't show any such issue and takes about 3 seconds to complete on Debian nodes.

This is surprising because -T 1 means timeout 1s.
How did you check that it was ssh-keyscan the culprit ?

It's been a while, but it was running « rudder agent inventory -v »
It was displaying something as « Running `ssh-keyscan -T 1 127.0.0.1` ... » and stopping there for minutes.
