What were you trying to do that didn't work?

A customer is requesting to backport 2 systemd parameters to RHEL 9. 

SYSTEMD_DEFAULT_MOUNT_RATE_LIMIT_BURST
SYSTEMD_DEFAULT_MOUNT_RATE_LIMIT_INTERVAL_SEC 

What is the impact of this issue to you?

These two parameters may improve the performance of a system that has hundreds of mount points and the mounts change frequently.
